Meh...
Has its points, but I liked music well before rockband and guitar hero came out and think they are great games. I have seen some great bands in concert (AC/DC, AFI, Breaking Benjamin, Chevelle, Seether, Shinedown, and incubus to name a couple) and I think that there is absolutely nothing is wrong with these games. While I think anyone who considers themselves shredding a Guitar Hero Guitar is retarded, most people just like the game and playing a game to some of their favorite songs.
What I hate though is people bitching about how we should pick up a real instrument. I don't want to play guitar, because I could give a crap less about playing myself. I don't need to play to enjoy the music. I don't hear people from WW2 bitching about call of duty. I don't hear NFL players saying "go play in the NFL poser". Why can't people get over it, it's a way for the bands to make money. And unless your band plays gigs for free (you must blow ass), that is part of the reason people play music.
Good animation. Terrible message. Get a different to complain about, because you are bitching to a crowd of gamers.
