Madcow's recent journal revived the question that's been in my head for quite a while now.
Personally, I really can't grasp the point of mastering Guitar Hero, Rock Band or any other music-related game, simulating actual instruments. Even if actually fun, spending excessive ammounts of time on it is, putting it mildly, weird. You could toss in another ~100$ and grab a, say, used guitar for the price of the equipment needed to play those games. You could be learning to play an actual instrument instead grinding the ways of button-mashing and switch-flipping.
In short: If you actually have the time, effort and money, why stick with fake stuff instead of the real thing?
Enlighten me, please. :rly:
