So lately I have been teaching myself how to develop games with the XNA Game Studio(http://creators.xna.com). So far I am very impressed. The really cool thing with XNA is that you can write your code for the XBox 360, and by adding only a few extra lines of code for handling controls, your game will also work for the PC. That will also hold true for Windows Mobile 7.

Another really cool thing about XNA is that they give you all the tools you need, including Visual Studio Express, completely for free. That's right, no upfront costs involved in order to learn how to make games. That is awesome!

So far I have only done a couple of the tutorials, one for a 2D Game and another for a 3D game. All programing is handled in C# which is not as difficult as you might think.
