holy shit, Guitar Hero II.

[jas1n]

i can't be the only one hooked on this game. i haven't got a decent night's sleep since picking this up.

I love it, too, though I haven't played it in a while.

I'm afraid of picking it due the carpal tunnel I know I'll contract shortly afterwards.

Maybe for Christmas. :P
