Why didn't they do it this way the first time?

My simple point was that if you're going to make a game where the kid is supposed to follow fingerings on the "guitar" why not make it a real guitar and not some cheezy POS that only resembles one in shape? Think how many would be on their way to learning how to play if (as I said) they had done it this way from the beginning.

Derp.

The tech hasn't been there. Cheap and adequate signal processing technology for stringed instruments hasn't really been there for very long. I've tried numerous units on my laptop, all had perceivable lag, from a couple hundred milliseconds to nearly half a second, which makes it mostly unusable. I'm surprised they can even do it with the xbox well enough so the game doesn't lag all to hell.
