That wasn't my point either. I really don't think players should quit GH and go practise a real guitar. When you play FPS, it's not supposed to be better to get a gun and do real infiltration missions, so why it should be here ?
And I didn't say people don't learn correctly how to play guitar : I play Destruction Derby, and still I had my driving licence. So don't get me wrong. It's all but true when parents say the kids should spend more time on real instruments, because if there wasn't any GH, they would play something else. I'm sure most of them see GH as a game, not as a real way to make music. Therefore, I read somewhere that 19% of players say they started real playing after discovering the game. It's just a question of motivation : for some it's a song they wanna play, for others a video game, and I'm totally ok with that. In the end, GH allows you to have a part of the pleasure of playing without the training. You can have fun and play the rock star without knowing how to play, so why not ? I played it a few times, I suck at it, and I really don't like it, but there are many other things that I don't like, after all.
I know it's just a game, and I wouldn't be that angry if it was still just so : the shit is taking too much importance nowadays. First, this is not a musical game : it's a rythm game. You're not supposed to play the song right, but only to follow the colors on the screen. So it is more asking from the visual than the earing. To me, the Rock Band drum set is what the game should be : axed on rythm. Second : it doesn't respect at all the real notes you play on a guitar. You don't play Come As You Are by 4-4-1-5. When you're a guitar player, you have to "unlearn" your reflexes to play properly. Third : you cannot play whatever you want. You're guided by the game, and you can't modulate the playing as you like. The GH ads make you believe you play music, and this is dangerous to me : YOU'RE NOT, this game is not even close to playing music, it's just a dissimulated version of the most basic principle of gaming : pushing the right buttons at the right moment. And don't tell me the kids can discover metal with this : if everything you know about Metallica is how to play One on extreme mode, you obviously know nothing.
4th (and major point) : to me, it contributes to the ruin of rock music. Seriously, Kurt Cobain as a playable character ? That would be the opposite to what he wanted. All the noise around GH is nothing but promotion, music industry, glitters, so far from what rock really is. It's like selling Pink Floyd on the iTunes store : totally pointless.
The rock culture is almost dead, and making it a fashion thing is not helping. Rock is everywhere nowadays. Back in 1995, listening to rock music made of you an asocial and a weird guy. Today, I see 20yo girls wearing perfectos and Motorhead shirts, and they don't know one fucking song from the band. It's like this "geek" thing. Big glasses, jacket in pants, loving maths and computers was a nerd thing two years ago, today it's the new black.
I think it would be cool to get the rock culture back today, but it's only a clothing mode. Girls who are "rock since birth" were "hip hop" three years ago. GH is kinda the same to me : it's hype to pretend you're a rockhead and you're a big fan of Lamb Of God, but you only know one song from them, loser.
tl;dr : I don't care about the gaming process but the "rock" mode pisses me off.
