What would be your ultimate music game? Mine would be a Rock Band-esque game, but instead of actually playing the music, you create and serve as a manager for the band, and your band gains a selection of genre identity and you have to appeal to it, but you must appeal to your fanbase and you can choose some famous songs and have a simplistic but large tool to create various songs.

Oh, and I might post the song list later.

So, what about you?
