We don't know much about Project Spark except that it was probably one of the most interesting things on show during presser day at E3 this year. Microsoft describe the game as "a powerful, yet simple digital canvas on which to build and play your own worlds, stories, and games" -- a free-to-play Xbox product that takes on Sony's current-gen mantra of Play Create Share.
It's an intriguing concept, to be sure, and Microsoft are not the only ones looking to offer such a broad community-led gaming experience (Disney Infinity, anyone?), but you can signup to learn more and potentially get stuck into the beta right now. Just click here.
