From Wikipedia:
Patapon (パタポン, Patapon?) is a genre-straddling rhythm video game exclusively for the PlayStation Portable (PSP) handheld game console combining gameplay features of music and rhythm games, real-time tactics and God games. Presented in a cartoonish, silhouetted two-dimensional environment designed by Rolito, the player plays as an immaterial deity who commands an army of caricature tribal miniature creatures by beating traditional talking drums. The game was developed by Pyramid and produced by Japan Studios, the same studio that developed and produced Loco Roco.[1]
Tell ya, this game is so sustainable and have me feeling high by chanting PATAPATAPATAN PON, which means charging at the enemy. For somebody who never like rhythm getting stuck in my head, this game is a total winner man. I am waiting for my three months vacation to hog on to his PSP :p
