Rock Band Addiction

For my birthday, I received a copy of Rock Band for my PS2. It is a great game to become addicted to, taking time away from schoolwork and the like. I have played games like these before and they always interest me and raise questions. Personally, it makes me want to play my REAL guitar after I play a few songs. Does this happen to most people? I hope so. Just because you can play "Dead or Alive" on expert does not mean you can play it on the guitar for real; but isn't that the point of the game, to give those who have no musical gift to feel like they do? I'm not trying to be critical, considering I don't have much musical talent, but I hope that games like these create an interest in people to pick up a real instrument and learn it.
