i beat GH3 ..
my daughter and i have been playing doubles on GH3 quite a bit, she's getting real good ..
went into Best Buy on Sunday and looked at Rock Band .. she just started whaling away on the drums, doing the kick petal and everything .. took it home, set it up .. she loves it! .. we have a band, she's drums, i'm guitar ... beaten about 16 songs so far ..

lol.
she's doing real good on it, should post a youtube vid of a 5 year old whalin' away on drums ..
this is so gonna help her in a few years when i get her into guitar lessons on tempo ... who knows, maybe she'll want to do drums instead .. uh oh, more equipment.. hehe.
