In 30 years when the gamer generation becomes old, it won't be such an issue.
People were already saying that 30 years ago
But the situation is much better than then already. All kinds of people are playing games on their Wii's and iPhones and those just came out a few years ago.
I'm not defensive!
I dislike guitar hero myself. I don't understand why people feel the need to... pretend
about realism in digital media. If you wanna make digital music, make digital music, don't play a digital guitar. A guitar is but an ancient instrument - Software can do so much more.
Aren't games all about pretending though? I don't see why pretending to be a rockstar would be any different from a medieval warrior or whatever. Get a real sword.
