These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Game Breaker: The stud multiplier Red Bricks are easy to find and make the Lego City Hero ratings a matter of getting one purple stud. Thankfully, a lot of red bricks cannot be found until the endgame, or after the story is over.
One of the last upgrades, the jetpack, makes it possible to skip large sections of the main world's free runs.
What Do You Mean, It's for Kids?: Sure, it's a kinda Lighter and SofterGrand Theft Auto, but the humor is hard for kids to understand, you can steal cars, food, boats etc. Enemy astronauts's jetpacks explode making them return in pieces. Also many Shout Outs to adult movies. It's safe to say that this isn't a good game to build a child's morale, but to kids over 14 is it really awesome since they know the difference between right and wrong. And this is to say nothing of the fact that the player character is a police officer—not even an Anti-Hero type—who is allowed to cause all manner of collateral damage with no repercussions.
Visual Effects of Awesome: During the final level the scenery that Chase passes while skydiving to earth is nothing short of mindblowing.
