Katamari Damacy (塊魂, Katamari Damashii?, lit. "Clump Spirit") is a third-person puzzle-action video game published and developed by Namco for the PlayStation 2 video game console. It was first released in Japan on March 18, 2004, and was later released in South Korea on August 12, 2004, and in North America on September 2, 2004.
The game's plot concerns a tiny prince on a mission to rebuild the stars, constellations and Moon, which his father, the King of All Cosmos, has accidentally destroyed. This is achieved by rolling a magical, highly adhesive ball called a katamari around various locations, collecting increasingly larger objects, ranging from thumbtacks to schoolchildren to mountains, until the ball has grown large enough to become a star. The game falls under both the puzzle and action game genres, since strategy as well as dexterity are needed to complete a mission.
Katamari Damacy's story, characters, and settings are bizarre and heavily stylized, rarely attempting any semblance of realism, though the brands and items used are heavily based on those current in Japan during the game's production.
