im a GH fan (i LOVE IT on the PS2), but im not excited with the DS version... unless you can play it like the big versions (AKA: regular (face or whatever) button only as an additional control method), it a no go for me... i mean, im not goin out with such BIG thing on my hand, and scratchin the touch screen tryin to "emulate" strummin a guitar or something... i mean, if theres no optional control, somethin similar to taiko no tatsujin, i wont even bother considering on gettin this one.
