The first Xbox360 entry in a series of strange "katamari" games. The premise of the games is that you are the Prince, and to appease the King of All Cosmos, you must roll around a ball gathering things that stick to it. The ball can only pickup things that are a certain proportion of it's size and smaller. You begin by picking up paper clips and erasers, and are soon picking up cars, people, etc. The larger the ball, the better your score!
