I just realized that rock band can easly be broght to the Nintendo DS. I mean realy DS has every thing it needs and it would be a big sucksess i garente. Here are 3 reasons.

#1: the ds has a built in mic for the singing it is a good mic to.

#2: the drums can be done with the very responsive touch screen. The game can come with 2 little drum stick stylus'.

#3: The gutiar is easy it has allready been made. And it is great.

Im shure that it would be great. Im also shure that im not the first one to think of this
