Fun and crazy, but when it comes down too the core gameplay, it's too short.
This game is truly great fun. You can really high without a care, smash your opponents in to bits and, best of all, Go really, REALLY fast! There is your basic racing challenges: going through rings, passing gates and smashing opponents (kind of like burnout). The normal mode is different than most racing games. Instead of getting first in the race (which can still be done to score extra points) you must collect stars by doing tricks like running through trees without getting hit and drifting. You must have enough stars to win if you want to continue through the game.
There is a few unlockables (tracks, trucks, paint jobs) and a really fun versus mode but thats about it. You'll be done with this game in about 10 hours so just be glad that places like Blockbuster and Rodgers video exist.
