Players who've experienced Katamari Damacy and We Love Katamari will be familiar with the premise here: Players direct Prince, son of the King of All Cosmos, as he pushes a sticky ball around a variety of environments (seaside town, office desk, swimming pool, zoo), collecting hundreds of objects that litter the scene.
Players start by rolling small stuff, like thumbtacks, and as they progress they can roll up animals, people, and even continents. The objective is to collect enough of a single type of object -- loud, heavy, expensive, soft, etc. -- so that the katamari (the ball) can be turned into an island for a needy animal. Sound strange? It is. But it's completely addictive, too.
