Evidently, there are guitar players who see this game as an abhorration of musical performance, as those who do not play guitar can now revel in the virtual panties thrown on their virtual stage. But there's nothing wrong with the game - there are those who play both Guitar Hero and a real guitar, with equal relish... tasty, tasty relish.
The choice is up to you... keep in mind that, however wonderful you and your friends may think you sound, the music industry isn't all that easy to be part of. And no way you can have a problem with playing 'Bark At The Moon' as the fuckin' Grim Ripper.
Gamer: omfg stfu n00b talk to me when you can play Bark at the Moon on expert roflolol
Guitar player: You're gay
Gamer: I kno u r but wut am I roflololmao
Guitar Player: Oh yeah? Well I'd like to see you play Bark at the Moon on a REAL guitar. ::shreds 'Bark at the Moon' flawlessly on his electric guitar::
Gamer: ::overwhelmed by such awesomeness that he explodes and dies::
guitarist: Yeah, too bad a real guitar has 22 frets instead of 5 and 6 strings instead of one. Guitar Hero is for cock smoking fags.
me: Both of you are dumb fucks. Go cut your throats.
