Rayman Legends was supposed to be a Wii U-exclusive title, launching sometime during Nintendo's "extended launch window." In February, however, Ubisoft announced that the game would be ported to all consoles, and delayed the near-complete Wii U version so as to launch the game simultaneously on all platforms.
Early adopters of the Wii U were, understandably, upset. Ubisoft responded to the severe criticism, but only by releasing a new demo for the game on Wii U.
This week, the final release date for the game has been set. Rayman Legends will launch on Xbox 360, PlayStation 3, and Wii U on September 3 (August 30 in Europe), putting the game's launch just weeks before the release of Grand Theft Auto V.
In the meantime, Ubisoft is still trying to make things right with Wii U owners. The publisher has launched a new Rayman Legends Challenges app for the Wii U. The app is free and includes different challenge modes and randomly-generated levels that allow players to earn "cups," which unlock daily an weekly challenges.
