I would highly reccommend it. If you want a party game, thats the one to get.
I bought it along side monkey ball, (which i'm pretty disapointed with personally compared to the first game), and its fantastic and funny as hell.
Its life span will deterorate after you complete the main game and unlock everything but its really great fun for groups. Its fun on your own in the main game when your determined to unlock everything.
I'd say go for it. Its a little dark in concept in some places but is really really funny. Sorry have I already said that? lol
Go for it, but just make sure your arms are upto it!!!
