I got super monkey ball, a lot of the fun is having people make fun of you for having a "kid" game then you let them play a couple levels and they will be like OMFG!!! Its a true Hardcore game, most kids wont even have the patience to beat the levels, Mini games rock, you buy them with the points you earn in singler player. Everything is off the hook, i cant wait for tons of new different puzzles since you can jump in the new one, the game is full of tons of levels, and the new one i would imagine would have wayyy more, second one has like around 100 levels i think. 4 player multiplayer is the best and even if your friends arent interested in playing with a monkey's balls. =D You can play mini games, and with like 50 in the new one there should be a lot of mini games for everyone, check out IGN becuase every week their doing a mini game review, so far they have been cool with the newest one be the sweetest,
hope this was helpful!
