I bought this game. It's ok if you like DDR-like games.
I'm looking forward to trying Donkey Kong Jumgle Beat though. That one seems more interesting. Donkey Konga is a lot of fun if you have more than one person though.
I dunno. I kinda like it. But the songs are a little kiddy (i.e. pokemon theme, rock lobster, a medley of wheels on the bus and other songs, etc.).
