Came out today, and its retail price is just $19.99. Its a very fun, and addicting game. You basically control movement, with a sequence of buttons. Sorta like Parappa. You move them with one sequence, and then attack with another. Among other thing. There is a demo on the PSP store. Along with the GoW demo too. 
There are a ton of videos out for it, here is one; http://www.youtube.com/watch?v=lp173Si-XZM
9.2 from IGN; http://psp.ign.com/articles/852/852601p1.html (actual gameplay video in the review)
4 out of 5 stars from Gamespy; http://psp.gamespy.com/playsta.../patapon/853233p1.html
9.0 on Gamespot (9.2 user score); http://www.gamespot.com/psp/ac...=tabs&tag=tabs;reviews
Amazing to me that a game of this quality, is just $20. Highly recommended to anyone who has a PSP. Even with someone with no rhythm, I find it fun. Just get ready to get the music stuck in your head.
