Ok, this game has some fualts. The graphics aren't great. The game is repetitive. It's easy enough for your little brother to wrap.
You just have to check out the SWINGING! It's amazing. The entire city is generated, you can go wherever you want. There isn't even a load screen to slow you down. The rest of the game can be cool if you give it a chance. I've cleared the game and I still like to just swing aroung the city. You have to try it to believe it. They made a special physics engine just for this game, and it's perfect!
