Theatrhythm Final Fantasy: Curtain Call demo. The demo will let you sample two songs from the rhythm game, and players can transfer their save data to the full game, which launches September 16. Also on the Wii U this week are two strategy games, Cubemen 2 and the Virtual Console release of Nobunaga's Ambition.
On the 3DS side of things, the Virtual Console picks up Street Fighter 2010: The Final Fight, a futuristic NES action platformer that Capcom claims has something to do with Street Fighter's Ken. It's weird.
