Rock Band Better Than Guitar Hero III??

I asked my 17 year old son which he liked better, Rock Band or Guitar Hero III. His response, Rock Band. We picked up Rock Band a week ago for his birthday and frankly, I like Rock Band better also as I'm a drummer. Call me biased. The other cool thing about Rock Band is the multiplayer aspect of the game. Makes you feel as though you and your friends are part of a band trying to get your act together. What would make it even better? A few more instruments. What about a few more guitars. Would be a lot more fun if you could have 3 guitar players, a drummer and even a keyboard. What about a harmonica. I sense we are just seeing the tip of the iceberg when it comes to interactive musical games of the future. If you haven't tried out Rock Band, if you can find one, give it a try. I think you will enjoy it.
