I got suckered into buying this game because Gamestop didn't have any other racing games to choose from. But honestly this game is so bad I had to return it, it wasn't even worth the 5 dollars I paid for it used.
What we are introduced to is the same bumper-bowling physics we were used to in Need for Speed Carbon, with constant slipping and sliding into walls like "Disney CARS, the game", but with a damage model this time. The damage model isn't at all realistic, so when you hit a wall on the side, the back of your car may look dented. But, at least it is there.
The main problem of this game is the overall feel of it. The actual cover art of the game looks very nice, but once you get into the actual game itself...The art style is very cartoony (nothing inherently wrong with cartoons), but very terribly stylyized. It just feels incredibly sloppy and an eyesore to look at. Lots of browns and yellow-greens. And the characters just look incredibly stupid and also eyesores. The game just makes you feel uncomfortable, especially the physics...feels like you are playing some kiddie game where you are bumper bowling into walls with kiddie-physics, annoying sound fx/crappy music and eyesore levels.
My advice, dump this game in a chemical sewer where it would feel at home.
