Rockband 

Popular music video game. You can buy up to four game controllers for this game including a bass, a drum set, a guitar and a microphone. The game is funnest when you have four players and like that you have the actual rock band feel. The game is similar to Guitar hero but the difference is you can have a drummer, bassist, and a singer.

My friends like playing Rockband instead of forming their own real rock band.
