Looks like the xbox version will be the best
According to IGN
"a brand new 2-4 player "button basher" known as All You Can Eat will feature 'the Fat Kid.'" "A new replay function will also allow players to rewind the level they just finished so that they can jump back into the action at any point. It's a great way to save some lives as long as you can keep from dying as you might have done the first time. Finally, Xbox players will be treated to Live functionality that enables them the ability to download additional levels for their PDA mini-game and set score rankings in various categories like quickest time, highest kills, buildings destroyed, and so forth."
Now if only someone decide to bring it to the US...
