Not everybody wants to learn to play a real guitar though. I play Guitar Hero for fun and entertainment as she clearly states in her post. It's literally just a game and it never pretends to be a way to learn how to play a real guitar. And when I've played it for a few weeks, I can put it down and play another game from my massive collection without the guilt associated with buying a guitar and the USB interface needed for Rocksmith and feeling like I've abandoned yet another hobby. Guitar Hero is guilt-free fun. That's valuable in itself.
