Terrible, terrible game.
The graphics are horrid. The models all look like they are made out of alluminum cans and there is clipping everywhere.
The music is also horrid. It's generic rap beats with some techno.
The gameplay is even worse. Imagine the classic Cruis'n games, but terrible. The controls simply ruin the game, they are either too responsive, or not responsive enough. Oh, and don't bother trying to change to a different sensitivity, both settings are terrible. The loading times are unacceptable for a Wii game, they rival original Playstation loading times. Also, forget about tryign to use Nitrous, because an annoying announcer comes over the speakers and says NITROUSSSSSSSSSSSSSSSSSSSSs while the whole screen is blocked by the word NITROUS. The framerate is rather solid, until you go into split screen, and don't even think about trying to change the song while in split screen. If the car on the other screen is going off a jump and landing and you change the song, the car will simply fall through the road.
Yeah, I wasted $8.something renting this game. If I wasn't the first person to rent this game from my local store, I would have brought it back and said it didn't work, and switched it for a different game.
