For our campus events we've been showing the new XNA Express tools to create X-Box type games and the such. I found that the environment was very easy to use, and with a little digging into it I'm able to create my own games and have some fun doing it. Thought I'd let you know that i've posted the code for the demo game, and you can download it from my website - www.BenkoTIPS.com and clicking on the downloads menu.
Registered users can get the code examples for this and other webcasts and presentations we've done over the last couple years. Maybe you'll find something you can use?
