Disney has released the trailer for their upcoming Disney Infinity, due out this summer. The game lets you import figurines you buy into the game, a la Skylanders. Disney Infinity comes with Jack Sparrow, Sully, and Mr. Incredible, but any figurine you buy from the series can be put into your game.
This game actually looks pretty cool. It's open-world and allows for mashups of all sorts of Disney and Pixar characters. Honestly, I think this will be a great game for kids, especially since it looks like it will really encourage and reward creativity. The trailer showcases some of the gameplay and worldbuilding capabilities, and it looks pretty impressive. The only clear downside is that, since adding characters requires buying new figurines, the full experience of this game will end up costing quite a bit.
