Premise
Dance Hero. Pretty simple concept. A dance is shown and you need to mimic it(a pre-song demonstration is available to explain the different moves that will be used). Difficulty levels adjust the different moves that need to be performed. Downloadable songs, team dancing(online and off), career mode, etc. Online teams can form like step groups and can challenge other groups. During certain points in the song, freestyle sections are available where players can do moves and get points based on what they are doing.
Custom songs and dances can be uploaded.
