Super Monkey Ball: Step & Roll

Super Monkey Ball: Step & Roll, like its predecessor Super Monkey Ball: Banana Blitz, is a fun ball rolling game with a number of challenges and a bunch of mini-games. There are a few nice elements like the Super Mario Galaxy-like co-op mode where other players can shoot obstacles out of the way. The addition of balance board support wasn't a big selling point for me - on paper it sounds like a match made in heaven, but in practice it's just a big load of frustration. If you ditch the balance board support, you'll have a good time.
