Summary: Highly addictive game, fun for a very little time but easy to beat and waaay to short. The other half of the game is on XBOX Live market place and it has to be bought for a total of at least $20.00 worth of Microsoft points. Same principle as any of the prior Katamari games. Achievements are very easy to get. Online multiplayer and co-op look like there was not that much effort put into them but it could be fun the first few times. Ideal for kids.
