I play IIDX and pop'n music, and I like Gitaroo Man as well. I've also played stuff like Parappa, Um Jammer Lammy, and frequency, all of which pleasantly surprised me.

gitaroo man is sweet ^^
but that's about the only other music/rythm game i play exept for ddr, or dancing stage as they have chosen to call it here in eu...

I play beatmania, although, it's as hectic as hell. Does anyone know when iidx12 is coming out? The new character girl looks hawt.

I like Gitarro man
