Make your own games for the XBOX 360
This came through a couple of weeks ago (before Tech Ed anyway), but I'm just getting to it.
You may have heard of XNA? XNA is a development framework for developing games for Windows and XBOX 360.
We announced a few weeks ago XNA Game Studio Express which is a set of tools available to allow end users to create games for the XBOX 360, as well as for PC's.
To get started you'll need some knowledge of C# 2005. You'll also want to check out the XNA developer center at https://msdn.microsoft.com/xna.
