This game could have been a decent copy cat of Mario Kart if not for its extreme difficulty. Even in rookie mode the races were difficult. I can't imagine the tougher difficulties. So much potential wasted. For those looking to boost your gamerscore stay far away from this. The first 50G are easy but the rest will tax you or may not be possible to get. 2 achievements are online only and the online is a ghost town.
So here is the story. Jimmie John, who is either a hero sandwich chain store owner or a racecar driver, or something, I don't know and I really didn't care to do any research because the game was like trying to high five a bag of broken glass.
The weapon system gets pretty repetitive as does the ol timey pit crew captain that keeps reminding you that you can't use that weapon till the crowd unlocks them for you.
The difficulty settings are completely out of whack, I played on Rookie (easy) because I was just looking for some quick gamerscore but the AI regularly beat me like an inner city mugger.
The game stays fun and original for about 10 minutes, than it gets old and tired like a steak from the Olive Garden.
