Is THAT many options on a poll really necessary? 3 would suffice methinks.
why not spend all those hours learning an actual instrument?
Now, I don't play it. But it makes more sense to play this than taking the insane amount of hours needed to learn a "real" instrument.
The game is cheaper, faster to learn, and easy to throw away.
A real Guitar takes commitment.
Some people don't want that. They want to easy way. Fine. But no one is impressed with it other than other Guitar Hero players. And that's the trade-off.
