ive been playing guitar for about the last 10 years or so, and it doesnt bother me at all...its just a game. i dont play call of duty and brag about being an expert sniper because im good at the game...or think i can scale mountains because i beat tomb raider...or think i can be in the NFL because i beat a season on all madden. just play and have fun....thats what games are for
im guesing you havent tried the game, and im hoping you arent avoiding it because of things people say. while its not the same as guitar playing, some of the mechanics are the same... basic things as finger movements, coordination between hands and rythym, and the use of the whammy is fairly accurate. i can honestly say im a pretty decent guitar player, but expert level on guitar hero is way too much for me to handle. its just a different sort of thing really.
so i send you and your friends a challenge to play this bad boy....set it to expert or even hard....and come back and let me know how it went
