Fucking hell, I might have to get a PSP because of this game.
It looks awesome. Of course, I'm a sucker for weird, offbeat Japanese stuff that doesn't fit in with the usual genres. If you can't tell from the trailer, it's essentially a rhythm-based RTS, where all the unit commands are mapped to drum beats that you perform with the face buttons. Staying in time with the beat makes your units perform better, and you unlock new chants and unit types as you progress through the game. It's made by the same guys as Loco Roco, for those of you familiar with that. Anyway, it just came out in Japan a few days ago, and it's due out in February in the States, and I'm really looking forward to seeing how it turns out.
