The Ringworld is the final and most mighty of the titanic projects available for construction in the new Megastructures expansion for Galactic Civilizations IV: Supernova, allowing the fabrication of a perfect artificial world in the shape of a ring, wrapped around a hosting star, for the people of your Civilization to settle and work on.

While not quite the crown of the Megastructures research tree (that accolade is reserved for the final level of Augments for the Stellar Nexus) the Ringworld is hi-tech stuff and takes a significant research investiture to achieve.

The Ringworld will also require a non-trivial amount of Gigamass to manifest, both for the Megastructure itself and to construct the Dyson Sphere required to power it. As such, the undertaking of such a magnificent project must not be taken lightly and you’ll need to decide whether a new super-planet is a better fit for your Civilization’s current needs than a Stellar Nexus with Augments or a set of Stellar Gates. While the performance enhancing bonuses granted by an Augment will be game-changing, it’s also quite difficult to quantify just how useful a massive, highly customizable artificial planet-like structure can be on your game.

Here’s a virgin Ringworld, pristine and sparkling with potential, before a clumsy uncultured barbarian like myself has had a chance to maul it with his crude designs.

You’ll note that this creates a colonized “planet” with very high Planetary Input values, and 39 tiles to build on, with a mix of useful tile types to allow you to really get the most out of that landmass. What you build on this magnificent Megastructure, is completely up to you!

Do you build one out of necessity, because your exploding Mimot population has colonized every last world in your territory and you’re not quite ready to go to war with a neighbor for their own planets? Or do you plan on building an almighty armada to bring a war of destruction to all around you, and so fabricate a world dedicated to industrial might and shipbuilding?

Let’s take a look at a couple of Ringworlds built for different purposes, and hopefully whet your appetite for the possibilities they offer in a variety of situations.

Firstly, let’s take a look at one I built in my own game as the Corporate Sector.

As you can see from the screenshot, this was right at the close of the game with the CS, where my main goals were to accumulate enough Credits to keep my greedy money-grubbing Iridium Citizens happy and ensure I had the proverbial “Sinews of War” to ensure no other Civilization could best me in a war. Unless you’re solely relying on Supply Ships, constructed and flown in from off-world, you’ll often want some Industry on a Core World to get everything else up and running.

Over at the east end of the planet I built a fairly solid core of Industrial Districts surrounding a Stellar Forge, for a substantial Manufacturing score. I used Supply Ships to get this going quickly, while interspersing this industrial development with Housing, allowing Citizens who were outgrowing their own worlds to be transported over to rapidly fill this new planet. You’ll not usually get such a high Manufacturing score unless you manage to conquer the Yor’s homeworld of Iconia, or find a very high class planet and dedicate it to industry and Workers.

The rest of the planet was then filled with Income boosting Districts and Improvements, with a substantial proportion of the population assigned over to the Entrepreneur Job. Sure, there are some big end-game technologies in play here, such as Individual Divinity, and the boost that’s giving to Citizens is inflating these Planetary Outputs a little, but you’ll see that this one Ringworld is producing a massive 431 Credits per month alone (taxed at about 40% for 151 Credits per month).

If you really want to, you can fill it full of Approval boosting Improvements to get that tax-rate up even further, but even without those, I pushed the tax-rate to the maximum of 75% here, and despite this eyewatering assault on our Citizen’s wages, we’re still able to get a respectable 71% Approval rate and a 324 Credit per month Income, just for this one planet.

And I’m not even trying here: I’m sure all you minmaxers out there are going to have a lot of fun figuring out how to really powerhouse your economy with these Ringworlds. If you dropped the industry, relied on Supply Ships and then just covered the planet with Housing and economic assets, I’m sure you could do a whole lot better than this.

Now let’s take a look at Ringworld dedicated to a completely different purpose.

I don’t need to explain this one too much, it’s built to pump out the biggest, most dangerous battleships as fast as possible, while still generating some Wealth, with some Entertainment Districts to counteract the inevitable Pollution that accumulates on a big dirty industrial world like this. You’ll note there are no special industrial Improvements here, this is mostly just Manufacturing Districts and a bunch of Workers.

And this is one of the Iridium’s prized War Bringer Battleship models, being pumped out in a mere two turns because of that massive Military score.

These are extreme examples I’ve shown you, where I’ve really tried to build for one specific effect. Now, you’re going to have to get your thinking heads on (or make a spreadsheet) if you want to work out whether the Manufacturing output you’d get from a Ringworld would be better value for you than a well Augmented Stellar Nexus and the product modifier it adds to you Manufacturing right across your Civilization.

Which one is better is going to vary greatly depending on your own in-game circumstances, but the Ringworld has some advantages that the Stellar Nexus does not.

Firstly, the Ringworld is much more difficult to remove from the game than the other Megastructures, as it must be successfully sieged and conquered. Of course, if you do lose it, your enemy can take it off you, and they’ll have access to all that infrastructure (and the Citizens) housed on it.

The other advantage is that the Ringworld can benefit you in a much more multidimensional way: you don’t need to pile everything into just Income or Manufacturing like I’ve alluded to here: you can build a more balanced Core World from it, and if you’ve saved some of the best Civilization Achievements for this world too, the Planetary Output values you can get from it can be truly staggering.

The latest DLC for Galactic Civilizations IV arrived earlier this month, introducing a host of powerful new Megastructures. In this week's dev journal, we're diving deep into another of this expansion's titular Megastructures: The Stellar Gateway.

Stellar Gateways are massive portals that utilize the reality-warping power of black holes to create connections between distant points in space. These powerful Megastructures are ideal for expanding to distant corners of the galaxy, establishing extended trade routes, or rapidly redeploying fleets.

Stellar Gateways are unlocked by the "Advance Nexus Augments" technology and are the third Megastructure to be unlocked by the DLC, following Dyson Spheres and Stellar Nexuses.

Stellar Gateways are constructed around the perimeter of black holes by new Stellar Architect ships using a resource called Gigamass. Each Gateway takes 8 turns to construct.

Building a Stellar Gateway requires 30 Gigamass, a finite resource collected by Planetary Harvester ships from dead planets. Each additional Gateway requires another 30 Gigamass, so you will need to consider the benefits provided by a new Gateway pair compared to other similarly priced Megastructures like Stellar Nexuses.

Once a second Gateway is completed, it will automatically pair with the first. Sending a fleet through one Gateway in a pair will instantly transport it out the other. Additionally, fleets will automatically consider Gateways when pathfinding/looking for the shortest route to a location.

To make navigating Stellar Gateways easier, we’ve added a convenient button to the Gateway Context Window. Clicking this button will instantly move the camera to and select the other end of the Gateway pair.

As you build more Gateways, you may want to reorganize, break, or form new gateway pairs. This can be done easily from a new tab in the Automation window accessible from the main screen hot bar.

Note: Stellar Gateways can be invaded and captured, and thus will need to be defended.

Fleets can be stationed on Stellar Gateways by turning them “on” or “off” via this toggle on the Stellar Gateway context window. While turned “off”, fleets will be stationed on the Gateway instead of being sent through - allowing you to fend off any would-be Gateway thieves. The Gateway’s current state can be seen at a glance using the icons overtop the Gateway itself. A Gateway being “off” will not prevent fleets coming through from the other end.

As stated before, Stellar Gateways are excellent tools for expansion, trade, and warfare. The ability to funnel new fleets straight from shipyards to far-out frontiers can be a game changer. Additionally, consider that the reverse is true - a military on campaign can return to the defense of your otherwise undefended core worlds and capital in a fraction of the time it would normally.

Having a strong network of Stellar Gateways can also be a diplomatic boon as you can establish the new Gateway Treaty with your allies - allowing them to use any of your Gateways and you theirs.

A well-placed Gateway will let you take your enemies by surprise with an invasion launched far behind enemy lines or it can allow you to resupply your invasion force with no delay. Altogether, Stellar Gateways are a powerful tool for any playstyle. The increased mobility that even a single pair of gateways provides can be extremely useful - especially on larger maps or games with multiple sectors.

As you explore the new features of Galactic Civilizations IV: Megastructures, consider the strategic possibilities offered by the Stellar Gateway. Whether you're expanding your empire or bolstering your defenses, the Stellar Gateway provides a versatile tool to enhance your civilization's strengths.

We invite you to share your favorite new strategies with us. How will you leverage the power of the Stellar Gateway to shape your galactic empire? Will you focus on rapid expansion, military dominance, or perhaps a thriving economy? The choice is yours, and we can't wait to see the creative ways you'll use these Megastructures to achieve victory.

Stay tuned for more insights and updates in our future dev journals. Until then, may your civilizations prosper and your stars shine brightly!

The Megastructures expansion has two new resources for you to play with: Energy and Gigamass. We briefly covered both back in developer journal #84, but today I’d like to focus on Gigamass.

Gigamass is a limited, somewhat scarce and very valuable resource, being tied to the Dead Worlds found orbiting the various stars on the game map. Aside from a very small amount that can be gained from Events here and there, once the galaxy’s supply is used up, there’ll be no more.

The race to harvest Gigamass is important, and once you have laid your hands on some, the choices you make on what to spend it on is a key part of the gameplay. You’ll not usually own enough to build everything you could hope for in a single playthrough and that is by design, as the gameplay features that Gigamass offer are very powerful in their effect of boosting each of the core mechanics of GalCiv.

Whether that’s allowing you to field incredibly powerful warships to conquer your more peaceful neighbours, apply a huge boost to your economic or industrial output with Stellar Nexus, linking together distant parts of your civilization’s territory with Stellar Gateways and many more, the intention is for you to pick the aspect of your civilization that you want to enhance and then wisely spend your available Gigamass to achieve that purpose.

One of the challenges in making a space 4X game fun is ensuring that each playthrough is unique, even if you’re playing with the same faction or game settings each time. Procedurally generated content does the heavy lifting there but are some other tools to achieve a similar effect.

The various Strategic Resources in GalCiv IV, with their many uses and random distribution, is one way to ensure this: for example, a Civilization with naturally weak research can enjoy access to a plentiful supply of Promethium by spending it on Research Missions. That Promethium can further shape their ship-building program too, encouraging the construction of Cloaking Devices, Promethium Drives and so on.

If Elerium is more abundant, you’ll have great access to the very best Beam and Shielding technologies instead.

With Gigamass however, we wanted to add an even more scarce resource into the game that gave the player much greater power, but would require them to make tough choices on exactly how to spend it. Promethium and Elerium can be purchased from the bazaar, and so even a player without any mines of their own can build their economy up and often still buy those resources in smaller amounts, and it can often be traded with another Civilization who does have access to it.

Gigamass is deliberately more difficult to get: you can trade it with the other Civilizations but it is valued much higher than the other Strategic Resources in the base-game. We’re hoping that the fight to reach the Gigamass, and then control who owns or has access to it afterwards, will make compelling gameplay that not only gives you some very powerful tools to utilise in your playthroughs, but also provide a new, optional focal point to encourage you to really get engaged with the core mechanics in new and exciting ways.

You’re playing the Korath Clan and don’t quite have the Gigamass available to build one of those big, shiny Megastructure baubles the other Civilizations are showing off? Then spend yours on building some of the smaller, cheaper Civilization Achievements that require Gigamass and Energy to turbocharge your industry, and then spend the rest on a set of nearly invulnerable ships to go take those hi-tech treasures off them instead. That way you get the fruits of their labours too!

If you’re trying to play more peacefully, perhaps a short war to grab a Purple Star could be well worth the effort: a Stellar Nexus here could provide a huge boost to Influence, Tourism, Trade Routes or Diplomacy, depending on the Augment you pick for it.

In most games on medium maps with more standard settings, you’ll have to pick and choose which Megastructures you want, as you’ll be unlikely to be able to afford them all.

However, GalCiv is a sandbox-like 4X, meaning that it is highly customisable and gameplay can vary quite significantly depending on the game options you set. This affects Gigamass too: larger maps with less AI player populating it will generally mean you’ve got more Gigamass (and Stars to build your Megastructures around) than you would with a smaller, more densely populated one.

So, if you’re excited to play a game with the new expansion and you’d like the option to build more of those titanic, powerful construction projects, playing on a larger map, and/or reducing the amount of AI opponents is one way to guarantee more Gigamass for an epic playthrough with many powerful Megastructures available in your game!

Let us know how you get on with your own Megastructure projects, we’re excited to hear how you are incorporating them into your own playstyle.

Cheers!

The long-awaited DLC for Galactic Civilizations IV has arrived, bringing with it a plethora of powerful new Megastructures. In this week's dev journal, we're diving deep into one of the expansion's titular Megastructures: The Stellar Nexus.

Stellar Nexuses are colossal, versatile Megastructures constructed around stars. Each Nexus offers incredible bonuses to fleets and colonies across your civilization, tailored to your chosen Nexus Augment.

Unlocking Stellar Nexuses requires the “Megastructure Nexi” technology.

Once researched, your Stellar Architect ships can build Stellar Nexuses around Yellow, Red, Blue, or Purple stars. The color of your Nexus' host star matters as it will dictate the type of bonuses your Stellar Nexus can provide.

Building a base Stellar Nexus demands 50 Gigamass and takes your Architect 12 turns to complete.

Upon completion, you can manage your Stellar Nexus by double-clicking the Nexus or by clicking the “Manage Megastructure” button from the Nexus Context Window.

From the management screen, you can view the effects of the base Stellar Nexus and explore the list of available Nexus Augments. At its base level, the Stellar Nexus provides a not-insubstantial 5% boost to approval, research, and manufacturing for all colonies across your civilization.

In addition to enabling the construction of Stellar Nexuses, the Megastructure Nexi technology unlocks 16 base-level Nexus Augments—four for each star color. The list of Available Augments can be located beneath the Nexus' current effects in the bottom right portion of the Nexus screen.

Even at the base level, Nexus Augments provide substantial bonuses. An upgraded Stellar Nexus can significantly accelerate the development of your empire.

The cost of installing a base-level Nexus Augment is 15 Gigamass and 10 Energy, with the installation process taking 4 turns to complete.

There are 48 total Nexus Augments—12 per star color and 16 per tier. The Augments available to a Stellar Nexus are determined by the color of the star it's built on, with each star focusing on a different kind of bonus.


A unique feature of the Stellar Nexus is the ability to change the installed Augment at any time by choosing an Augment to Retrofit. This process takes the same amount of time as the initial installation, but you'll be refunded the Gigamass cost of the original Augment, ensuring you only sacrifice time, not resources.

Stellar Nexuses are designed to be flexible, adapting to your civilization's evolving needs as the game progresses. For instance, a civilization focused on colonizing new planets might prioritize the additional Food and accelerated Growth from the Flourishing Garden Augment. Conversely, a civilization engaged in warfare might opt for the Twilight Engine to expedite fleet production.

With sufficient Gigamass, players can construct multiple Stellar Nexuses for compounding or synergistic effects. Augments on stars of the same color often complement each other, such as the Subspace Lens and Galactic Gateway Augments on Purple stars, which can significantly boost your civilization’s tourism revenue.

Critically, bonuses from Nexuses can stack, allowing a focused player to construct multiple Nexuses with the same Augment. This can be a compelling strategy with a steep opportunity cost: requiring you to ignore other powerful Augments.

Finally, Stellar Nexuses are crafted to seamlessly fit into your preferred playstyle. Civilizations like the Phalenoids, who leverage Influence, can greatly benefit from the Subspace Lens. Research-focused civilizations like the Yor might favor the Quantum Mirror or Neoteric Spire, while the Mimot, reliant on rapid Growth, would find the additional Population Capacity from the Celestial Garden advantageous.

As you explore the new features of Galactic Civilizations IV: Megastructures, consider the strategic possibilities offered by the Stellar Nexus. Whether you're expanding your empire, bolstering your defenses, or advancing your technological prowess, the Stellar Nexus provides a versatile tool to enhance your civilization's strengths.

We invite you to share your favorite new combinations and strategies with us. How will you leverage the power of the Stellar Nexus to shape your galactic empire? Will you focus on rapid expansion, military dominance, or perhaps a thriving economy? The choice is yours, and we can't wait to see the creative ways you'll use these Megastructures to achieve victory.

Stay tuned for more insights and updates in our future dev journals. Until then, may your civilizations prosper and your stars shine brightly!

The next technological leap for galactic empires is here. Today, Stardock officially releases Galactic Civilizations IV: Megastructures, bringing new opportunities for players to harness the power of stars and create powerful late-game structures.

“Megastructures brings powerful new late-game options that we think players will really enjoy,” said Brad Wardell, CEO, Stardock Entertainment. “Too often in 4X strategy games, trailing players have their fate set near the end of the game; but with Megastructures we give players the opportunity to turn the tables on those sitting comfortably in first.”

While Megastructures can be beneficial, they will present their own challenges with resource management and political situations to navigate. Savvy players who are able to effectively allocate their materials will be able to harness the full potential of Dyson Spheres, Ringworlds, the Stellar Nexus, and Stellar Gateways to achieve ultimate victory!

The pinnacle of technology, Megastructures are powerful structures capable of tipping the cosmic scales in your favor. Each Megastructure has something unique to offer and your decision on which to build can have drastic implications.

Dyson Spheres are the ultimate energy engines that drive your civilization’s evolution through fueling massive Megastructures that redefine your empire. The color of a Dyson Sphere’s host star dictates its potential Energy Output making Energy-rich white stars a valuable resource.

The Stellar Nexus will be the core of your civilization and can be customized to become a Megastructure with many possible powerful benefits. A Stellar Nexus can be upgraded into a powerful new form by installing a Nexus Augment. These Nexus Augments provide various potent effects based on the color of the Nexus' host star and are divided into three tiers denoting the strength and range of their effects.

Instantly link distant black holes to revolutionize travel. These powerful Megastructures develop new avenues for military maneuvering, rapid expansion, and even extended trade routes. Additionally, civilizations with Stellar Gateways can forge greater alliances with the Open Gateways Treaty which will allow fleets from either faction to utilize their respective Gateways.

Build colossal, Class 39 artificial ring planets to house immense populations and secure your civilization’s future. Much like the Stellar Nexus, Ringworlds are influenced by the color of their host stars and provide different tile bonuses accordingly. By constructing these gigantic habitable rings, you can ensure that your civilization will never run out of planets to inhabit and forever make your mark on the galaxy.

Uncover cosmic secrets with all new quests and events designed to introduce the awesome features of Galactic Civilizations IV’s latest expansion. Discover Ruined Ringworlds and use their ancient technology to make powerful breakthroughs in Megastructure engineering.

• New Improvements: Harness ancient Ringworld technology to create powerful new Improvements to enhance your colonies and outpace the competition.
  
• New Orbitals: Further utilize the technology found in Ruined Ringworlds to extend the reach of your colonies beyond by building new Orbital Improvements. Additionally, the same technology can now be used to upgrade existing Orbital Improvements to create unstoppable colonies and core worlds.
  
• New Ship Components: Build bigger, more powerful ships using cutting-edge technologies inspired by this ancient race of builders.

Each megastructure presents unique benefits and challenges, requiring careful planning and resource management to meet your empire's needs. As your influence grows, rival empires will take notice, leading to new diplomatic interactions, potential alliances, or conflicts. The Megastructures expansion invites players to think bigger and bolder, redefining the scale and scope of their galactic ambitions in Galactic Civilizations IV.

Megastructures is Stardock’s latest expansion for Galactic Civlizations IV: Supernova and boy is there a lot to cover! I have to keep things brief in these developer journals so today so I’ll be providing an overview of the core features that Megastructures brings to the game, with the intention to further deep dive into its various components later on.

Megastructures adds a new branch to the Engineering Tech tree, with a sequence of new Techs unlocking access to a new resource called Gigamass and all that can be made from it.

Gigamass is harvested from Dead Worlds (those with a Class of 0), by the new Planet Harvester ship.

One crucial point to note: Gigamass is a highly limited resource and once all the Dead Worlds on the map have been harvested, aside from some very small amounts generated through Events, that’s all there is. Gigamass is valuable but the AI may be willing to trade their own stocks if you have something they want in return, but generally speaking, it would be wise to carefully examine your own Gigamass stocks and the costs of each Megastructure (or other feature) when planning what you want to spend it on.

Gigamass isn’t the only new resource added: the enormous Megastructures and a whole host of new Civilization Achievements will require a constant power supply to run, which we’ve simply called Energy.

The maximum value here represents how many Energy points worth of Megastructure and Improvement can be run on a turn-by-turn basis. Exceeding this has maximum has severe consequences, so ensure you have enough Energy before you build Energy-sucking construction projects!

So how do you generate Energy? The first is with the new Solar Farm Improvement.

This requires a small amount of Gigamass to build and provides a small amount of Energy: perhaps best used for powering the other new Civilization Achievements requiring Gigamass to construct, such as this Precious Gem Synthesiser, an example of the new Civilization Achievements added with this expansion.

These might be helpful for civilizations that don’t want or need to build the Megastructures themselves, and to give players some powerful tools and fun tools to help kickstart their campaign a little earlier.

For greater power generation, you’ll need the first of our titular Megastructures: the Dyson Sphere!

First though we need a new type of construction ship to build Megastructures: the Stellar Architect.

Wrapped neatly around a star, the Dyson Sphere is a titanic construction that harnesses enough energy from its host to power your other Megastructure projects. Different star types will generate different levels of power.

Later on, the mighty Stellar Nexus become available for construction too. On their own these provide an impressive boost Civilization-wide boost to Approval, Manufacturing and Research, and this alone is worthy of the Gigamass investment.

That’s just the start though! They can be further extended with Augments, which require further Gigamass and Energy investment, and are available in three tiers, with later tiers unlocked later in the Tech tree. The type of Augments available for each Stellar Nexus is dependent upon the colour of its hosting star.

Above you can see the Cosmic Mirror Augment, which grants a huge +3 Technology to all your Core Worlds and Colonies, which will dramatically improve your overall Research.

For those more war-focused players, the Daybreak Engine provides a huge permanent boost to your Military output, speeding the creation of fleets, and providing every ship with increased Armor Rating and Shield Strength too. This makes smaller ships like Fighters, Bombers and Frigates very dangerous, and is perfect for when you need a lot of deadly ships constructed in a short space of time.

The current Augment can be upgraded for even better performance with later tier unlocks, or they can swapped out for a different Augment type completely whenever you like, although you will pay the Gigamass and Energy upkeep costs for this. Here we see the third tier Eclipse Engine and the improvement it gives to your Military, Armor Rating and Shield Strength. This is powerful stuff!

With the star classification affecting both Energy output for Dyson Spheres, and the kind of Augments available for a Stellar Nexus, and considering Dead Worlds are a source of the most precious resource in the game, there’s now more excitement in the discovery of star systems in the early phase of the game. We encourage you to carefully plan which stars to use for which Megastructures to achieve your goals of galactic domination!

Stellar Gateways are the next Megastructure type and must be constructed on the hexes surrounding a Black Hole.

When paired together, these epic-scale portals allow instantaneous travel from one to another, with the ability to link and unlink Stellar Gateways as needed, in the case that you’ve got an odd number of Gates, or you want to alter the destination of one of them.

The final Megastructure is the mighty Ringworld, the culmination of all the research you’ve put into these technological marvels. A gigantic ring is constructed to circle a star, with the inner edge made available for colonisation and the construction of many planetary Districts and Improvements.

This creates a perfect artificial Core World large enough to house many Citizens. It provides the very best tiles with space enough to construct your dream world. Fill it with factories, credit generating districts or farms, or build something even more exotic and specialised. Your imagination is the limit, and this Megastructure is perfect for Civilizations looking to peacefully expand the size of their empire in the mid and late game.

There are also some very powerful Ship Components for players to spend their precious Gigamass on too, and it may be that a war-like Civilizations such as the Korath Clan might prefer to direct this precious resource into their most favoured pastime instead of messing around with all that Megastructure stuff.

As you’d expect from a GalCiv expansion, Megastructures adds new in-game Events too.

This is just a very quick overview of the main features of Megastructures, and I hope this gives you some ideas for incorporating them into your playstyle!

Cheers!

Hey everyone! For this week’s Dev Journal, I’ve compiled a collection of handy tips and tricks to help you get your civilization rolling in the early game of Galactic Civilizations IV.

Galactic Civilizations IV is a complex strategy game that demands careful planning and strategic foresight. The early game sets the foundation for your civilization's success, and understanding the nuances of the game's mechanics can provide a significant advantage. This guide compiles a few essential tips and tricks to help you navigate the early stages of your journey to galactic dominance.


On Turn 1, leveraging Executive Orders can set a powerful precedent for your civilization's growth.

The free Colony ship provided by Draft Colonists is well worth any losses to Research or Manufacturing caused by the -2% Approval effect. An early colony within your Homeworld’s solar system will add Research, Wealth, or Manufacturing to your Homeworld’s Inputs with minimal Supply Attrition. An extra 2-3 Manufacturing or Research can slash Improvement build times and research turn lengths in the early game.

Telescope Takeover is another powerful Executive Order useful for scouting for high-class planets. Yellow stars often harbor these valuable planets, making them prime targets for early expansion.

Your Homeworld’s Capital City is a critical Improvement. One way to get ahead of the competition is by placing it on Turn 1. When the game starts, your Homeworld will have the Colonial Leadership Council in its queue which normally prevents other Improvements from being built. However, Capital Cities are unique in that they can be placed down immediately, bypassing the queue entirely.

Successfully constructing your Captial City on Turn 1 will net your civilization a host of benefits, including bonuses to Research, Manufacturing, Income, and Culture Points per Turn.

When the Colonial Leadership Council is completed on Turn 2, you gain access to the Leader screen where you can manage your civilization’s Leaders. Recruiting and assigning these Leaders to Minister positions can make a huge difference in the early game. Prioritize recruiting three Leaders: one with high Intelligence, one with high Social Skills, and one with high Diligence. These Leaders can then be assigned as Ministers for significant bonuses:

1. The Minister of Exploration increases the Moves of all your ships by 1.
   
2. The Minister of Technology unlocks an additional Random Discounted Tech slot.
   
3. The Minister of Colonization provides bonus Approval that translates to increased Research and Manufacturing across your civilization.

Choosing a Minister of Technology is particularly important as having one increases the odds that powerful technologies will receive discounted Research costs.

Focus your research efforts on Colonial Policies to gain early boosts with Policies like Coerced Colonization.

The +100% Growth can be invaluable and well worth the hit to Approval as the Planetary Outputs of your Core Worlds (Manufacturing, Research, Income) increase significantly with each additional Citizen.

Additionally, gaining a Cultural Trait early on can make a huge difference. Each civilization starts with a large discount for Traits in one ideology, but don’t be afraid to grab one or two Traits from other trees if the bonuses are appealing.

For Terran Players, the Individualism Trait “Independence” will be the cheapest option - granting a free Flag Ship useful for surveying more Anomalies than would normally be possible with just the starting Flag Ship “Discovery.” However, you may want to wait a few turns longer to save up for the Egalitarian Trait “Fairness” which provides three free Colony ships and can greatly accelerate early-game expansion.

Terran players may also want to prioritize colonizing Artemis as doing so triggers a colonization event that offers Culture Points as a reward.

Not all high-yield colonies need to become Core Worlds. Instead, use them to support your main planets. A not-too-distant colony can double a Core World’s Inputs with little to no Supply Attrition.

Setting a lower Tax Rate with the Tax Rate slider can allow you to boost Approval, thus increasing both Research and Manufacturing. Income lost by lower tax rates can be offset by Anomaly Events that can often yield substantial Credits.

Be cautious when specializing Citizens as Workers to avoid hindering early Research progress as Workers provide bonus Manufacturing but generate no Research. On the flip side, try to retain any scientists acquired, as their bonuses to Research can be substantial, and they are harder to come by.

Orbital Improvements are a powerful tool for getting your Core Worlds online faster. The Recruiting Station, specifically, is a cheap, Credits-only Orbital that provides a huge boost to Growth as early as turn 1.

After researching Universal Translator, Durantium can be purchased from the Bazaar for additional Orbital Improvements like the Colonization Center for additional Growth or the Atmospheric Cleanser for reduced Pollution.

Research Planetology and invest in Housing Districts, which provide +1 Adjacency Bonuses and increase Population Capacity. Housing Districts are extremely useful for improving a planet’s efficiency by raising the power of all surrounding Improvements and making space for more Citizens.

A highly populated Homeworld can be instrumental in kickstarting the development of other Core Worlds as Citizens of one world can be transported to another.

Additionally, one effective strategy for accelerating the development of new Core Worlds is to send Supply Ships. Supply Ships provide a resource called “Stored Goods” to any Core World they arrive at, which acts as bonus Manufacturing points that can reduce the amount of turns it takes to construct Improvements to just one.

New Core Worlds can use these Stored Goods to build Shipyards of their own, allowing them to construct more Supply Ships to further accelerate their development.

These strategies should help you establish a robust foundation for your civilization in Galactic Civilizations IV. Each decision in the early game can have far-reaching consequences, making it essential to plan carefully and adapt to the dynamic galactic landscape. By implementing these tips, you're well-equipped to lead your civilization to greatness.

I’d love to hear about other tips and techniques you employ when starting a new game! Feel free to share your strategies and experiences and I’ll see you again in my next Dev Journal.

In this week’s developer blog for Galactic Civilizations IV: Supernova it’s time to examine the endless hordes that make up the Mimot Brotherhood, without a doubt the Civilization with the most impressive ability to “go forth and multiply” in all of GalCiv.

When it comes to 4X games, eXpand is often one of the most important of the X’s in terms of winning a campaign: territory gained in the early game often translates directly into industrial output, and industrial output extending the reach of your military power projection, whether to take territory to win or defend yourself from the predations of others while you achieve some other, non-violent victory condition.

Galactic Civilizations IV: Supernova is a somewhat more complex affair because unlike most classic 4X games, the taller style of play can be viable owing to the unique Core World and Colony dynamic, which allows players to remain competitive with less managed worlds on some maps. That said, unless you’re really hemmed in by dangerous opponents from the start of the game, achieving a strong start with plenty of Core Worlds or Colonies will usually be a better idea than staying small, and there is no other Core Civilization quite like the Mimot Brotherhood for achieving this super-wide style of play.

Why? Because the Mimot have two very powerful Civilization Abilities that work in tandem to supercharge their expansion efforts.

Fertile grows Citizens at a rapid rate and provides access to a couple of extra techs that help boost Citizen production.

With Proliferation, the Mimot can send those Citizens out to settle new worlds twice as fast as any other non-prolific Civilization, as the “buy one, get one free” ship feature also affects Colony Ships, Constructors and other non-combat vessels. The Civilization Trait Fast +1 ensures their ships get where they’re going before their rivals, while Productive +1 gives the Mimot a big boost to Manufacturing to build everything faster too.

This pairing ensures the Mimot have many more options in reaching valuable colonies and strategic resources.

Given enough space to breathe, the Mimot Brotherhood can claim new worlds, strategic resources and other map features at an alarming rate. A good player who knows how to expand well will end up with a truly huge territory if not checked by another player in some way, and this makes the Mimot an incredibly fun Civilization to play as if, like me, you really enjoy the colony management aspect of the game and love watching a large empire grow.

There is a downside to all this rapid growth: the Mimot tend to run low on Food pretty quickly, and much of your Core Worlds' real-estate will be dedicated to housing and feeding your Citizens. The Mimot themselves aren’t the best Citizens and that Food consumption doesn’t get you much: your average fuzzball is kinda cute and entertaining, but he doesn’t know much about anything and rarely lifts a finger to get anything done either.

However, once you research Genetic Architecture, they’ll start pulling their weight properly and then you’ll be pretty glad you built homes for them all, as your Citizen-based industrial bonuses shoot through the roof.

The Civilization Policy Genetic Manipulation can help, and they have access to some unique Improvements that can help their stats too.

Mimot Citizens make unattractive immigrants to alien Civilizations: their incredible Growth rate coupled with low statistics feels like a bad deal, although slow growing Civilizations might benefit from their rapid reproduction rate, just to get some more hands on deck. Just know that unless you’ve also got access to Statistic boosters, those Mimot aren’t going to be too effective for building a strong economy.

Another problem the Mimot will run into is other players: their borders can expand quickly and border friction is a major cause of war declarations. Fortunately their Civilization Trait Likeable +2 gives them a huge +3 Diplomacy boost, which is the main reason they’re not constantly at war with every other nation they bump into.

Proliferation helps out if war does break out: sure, your battleships are smaller and less durable than their rivals, but you get two for every one you pay the Military points for. What the Mimot lose in individual combat strength, ship by ship, they more than make up for with the ability to literally be in two places at once, and the strategic options that this tactical agility grants them cannot be understated. And in combat, you get twice the firepower!


One time I remember invading the Mimot Brotherhood when playing as the Yor Singularity, only to be horrified to see just how many fleets began to pour over our border a few turns later. Sure, they’re not particularly strong fleets, but they just throw so many of them at you!

So, the Mimot are a strong option if you enjoy managing a wider, more populated Civilization, with lots of Citizens on lots of Core Worlds, with lots of border friction to deal with and lots of ships to throw at your enemies when they inevitably tire of your shenanigans.
