Do not underestimate this game.
ModNation Racers lets you do a lot. You can customize your kart and character and there's a lot of possibilities. Also there's a racing track creator, which is easy to use and is quite innovative.
ModNation Racers is really fun if you like games like Mario Kart. It has great online, great multiplayer and it's a really fun way to spend time with other people and your family. The game is really for everyone. It doesn't matter who you are.
The only negative thing about this game that is really annoying is that the loading times are way too long. I hope this gets fixed with a patch or something.
