Today at Microsoft's E3 press conference, it announced "Project Spark," an Xbox One game that encourages creativity and invites players to make their own games. A stage demonstration showed use of the new Kinect and a tablet to design the environment, and then creating behaviors for the various objects in the world.

The game puts on emphasis on sharing, letting other players tinker and build on your creations as well. The demonstration displayed a variety of game types that they've made internally during testing, to show off the flexibility of the tools.
