This game may seem shallow because of It's art direction and graphics but that is far from what this game is.
This game focuses on Content, Fun and all of your life's free time!
It bundles that good stuff into an incredible building and management game that you will never get bored of because of It's replayability and your need to improve with all of It's mechanics!

A couple positives I've had with the game since I started playing:
- the tutorial and menu's are smooth to navigate and learn.
- the enemy you can have the option of facing, "the natives" of the planet are original enough and are potentially a grave threat if undermined and not dealt with in the "early game".
- the graphics are mesmerising to stare at leading you to just stare at boilers and refineries sometimes.
- the environment changes from blue and vibrant to green and dead as you produce more pollution from the machines you build.
- the modding scene of this game is a HUGE part of what makes this game engaging and customising your experience to be easier, harder or with more content is amazing.

A couple negatives I've had with the game since I started playing:
- when customising game settings for starting a new world, achievements are limited or turned off which is a bummer if your into completing achievements for a game.
- if you are slow with building, planning or building your defences against "the natives" you can be caught off guard with your enemies evolution into stronger threats and have your game be "unbeatable" as you can no longer expand your factory to produce more materials or defend yourself, thus forcing you to start over from scratch with an earlier save or new save.
- when building, if you plan improperly sometimes it can be a pain to rip up your progress and start over with the building projects you have, but with the blueprint system you can save the layouts of your buildings so It's not that big of a problem.

That's the end of my review and I very much hope you do buy Factorio as It is an amazing game that will truly engage you and get you thinking.
