Well, see, I disagree with that view since GH is more game than simulation. Saying GH is a waste of time because it's not real guitar is like saying Need for Speed is a waste because it's not real street racing. It's a game. Jam Sessions, however, is basically a virtual guitar with all the lack of bells and whistles of a real guitar. It seems weird that people will play fake guitar with no game element on a tiny DS with a D-pad and touchscreen when they could be playing the same song on a real guitar with the same amount of effort. And it's more rewarding, too. I'm slowly learning to play acoustic guitar, and while it's not as simple as Jam Sessions, it's more fun. I mean, if I wanted to play guitar on my DS, I'd just wait for GH DS.
