Wii U owners can download Disney Infinity for free via the Nintendo eShop. Of course you'll still have to buy at least one Infinity figure and the game base that reads those figures into the game, at retail. The downloadable version of Disney Infinity for Wii U on the Nintendo eShop features the full game, multiplayer support, and Toy Box level design tools that work with the Wii U GamePad.
While we don't know exactly why Disney Interactive and developer Avalanche Software decided to release the original game for free to Wii U owners, we suspect it is to promote the September 23 release of the newest game - Disney Infinity 2.0 - for PlayStation 3, PlayStation 4, Wii U, Xbox 360 and Xbox One. Disney Infinity 2.0 features classic Disney characters such as Donald Duck, Jasmine, Aladdin, Stitch and Tinkerbell, and select Marvel heroes and villains.
