The First 15 Minutes of Just Dance 4 (Wii U)

Copied from MobyGames:

Just Dance 4 is the fourth main game in the dancing series where players are rated for their ability to mimic dance routines to popular songs.

New to the series are the dance quests where six missions are provided for a single song. By completing them mojo points, the in-game currency, are earned. Players can create dancer cards as a profile for favourite songs, best scores and completed challenges. The sweat mode from the previous game that counts calories has been developed into a fitness-like program with a different focus for each routine and they can last up to 40 minutes. It also includes warm-up and cool-down moments. Other game modes are the battle mode and dance mash-up mode.

Exclusive to the Wii U version is the puppet master mode where the GamePad is used to manipulate visuals, playlists and moves on the fly for up to four other players. It can also be used to write on the screen and to record pictures and videos.
