Just endless fun, literally cant go wrong with this game. Its GTA but Lego, like cmon thats genius

best time i ever had and will ever have high

"Lego City Undercover" is an action adventure game set in... Lego City.
The game has you playing as a wildcard police officer called "Chase McCain" whom tries to imprison his rival Rex Fury.

Horrible - Bad - Decent - Good - Amazing

These are mostly 50/50. At least 15 are story related, a bunch are for collectibles, and some are for challenges.
Whilst none of these are inherently difficult, some can be incredibly grindy and tedious to complete (e.g. all super builds).

Pros

• Disguises are distinctly different
  
• A lot of content
  
• Easy to pick up and play

Cons

• Bugs
  
• Unskippable cutscenes/animations (slightly helped with cheat codes)
  
• Pretty weak story

I overall enjoyed this game. It's fairly long for a Lego game (10-15hrs of story), and has a ton of extra content to grind through if you want to get 100% completion.

--Story
The main story definitely feels like one of the weakest parts to me. There's a ton of forced missions until you capture Rex, and most content is locked behind it. I didn't care for most of the characters as they often feel like overused tropes
(Ex. Honey being the braindead rich kid), which feel predictable and fairly bland. The game clearly doesn't take said story seriously, which is fair for a Lego game, but does definitely detract when it's an original game.

--Mechanics
The main set of abilities Chase can use are locked behind disguises. These are unlocked in story missions, opening up more and more of the world around you. These outfits all feel distinct and have abilities specific to them, which is nice. Switching outfits is done at the flick of a button, which does make them a bit spammed near the end. Comparatively to Lego Batman, these lose their "special" feeling due to the fact you need to use 5 different ones in the span of a minute. Some disguises like the robber also have constant usage, which makes a bunch of them feel left in the dust at times.

The cars in this game handle surprisingly smoothly, and give a very similar feeling to GTA5. Most obstacles are destroyable,
and rather just add to the brick multiplier. I did find vehicles having a nitro to be very inconsistent. All police vehicles, pizza scooters, and some select cars have these, which sometimes leaves you stuck with a slow car to traverse great distances.

On the topic of distance... Backtracking in this game is painful at times. Whilst you get better options later on, you'll often be left with slow cars, a painfully slow running speed, and massive distances to cover. This also shows clearly on climbing sections, as you have to sit through every grapple, parkour jump, ledge shimmy... Which can really be way too slow.

--Collectibles
There's too many collectibles for me to reasonably list, so I'll mention the main ones.

• Red bricks - the meat and potatoes of Lego games, these give you stud multipliers and the like
  
• Gold bricks - rewarded for doing basically anything
  
• Character tokens - bought after collecting to unlock 1 relevant, and over 200 irrelevant characters

Other collectibles are usually button mashing, driving to a certain location, building a superbuild, using an ability in a certain location, and reaching the highest points of the map. Most of these feel like pure filler to me and serve absolutely
0 purpose nor challenge. The fact animations for these can be incredibly long makes it painful to try and collect them. Add
to the fact that gold bricks have an animation of their own, and you'll be sitting through 5-20 seconds of "cutscene" for a collectible (of which there are roughly 350 I believe).

Lego GTA.

Either if you want to experience a Lego game with a lot of freedom, or if you love collecting stuff.
I would recommend it, but get it on sale.
