English Title: Minna Daisuki Katamari Damashii"Everyone's Favorite Katamari Damacy"! The sequel to the bizarre cult rolling-things-up-to-get-bigger-to-roll-up-bigger-things-to-get-even-bigger game. This is the one that came out in the US as We ♥ Katamari, and at this point, who doesn't know about Katamari at least in passing? Suffice to say, it's weird, highly Japanese, and has a bitchin' weird Japanese soundtrack.
