Here is a demo (1hr long):

Project is like a game that makes games. It has a very in-depth level creation system that uses a CUDA-like language.
Expected to be exclusive to XBOX 1 and Windows 8?
Anyone interested in this one? I certainly am, as I had the idea to create a game that makes games a long time ago, and only recently am learning programming. Difference between this game and mine is that mine would require no programming experiences (yes, it's possible).
The issue then becomes, "how much control do I really have" and that is the issue that is hard to solve.
But until then, Project Spark looks like a winner (But, Windows 8? Really?)
