http://ning.it/196Fj8v - I completed a book on game development, design and release. It teaches C#, XNA and many of the practical skills needed to manage your project, a team and even release a game. I had originally prepared it to get published and go to print, to teach at colleges for my classes, and for others, but over the last month, have decided to release it for free to the world as a download. Its target audience is ages 13-17, students still in school, interested in developing video games, but it is the same materials I use for adult classes as well.
Also, if you are interested, I'm working on a Course Guide to cover all 5 sections of the book. I'd also appreciate any help in preparing that, or ideas on how you might teach a particular section. Also, I'm completely open to recommendations and improvements.
It sounds interesting, I am downloading the book right now =)
Thanks for sharing
