Microsoft has announced Project Spark, a game that lets you build you very own digital world and then create new and original games within that world. You have control over everything, from the world’s geography down to the A.I. behavior of rocks.

Once you’re done designing and executing you ideas, you can share them with the rest of the game’s community. It will then take your idea and re-mix it, add to it or just enjoy playing it as it is.

Project Spark will be available on the Xbox One, Xbox 360 and Windows 8. Watch the introduction and some clever game ideas in the videos and screenshots below.
