Pata-Pata-Pon, I am incredibly addicted to Patapon! Get the demo here, play the demo, live the demo, sing during the demo, then buy the game. Seriously it is one of the best games I have ever played, kind of a rhythm game, meets a god sim, meets an rpg lite game, meets an rts, meets the wee free men. This game needs to be in as many hands as possible, to me this is a killer app for the PSP. BUY IT!!
