      • I'm interested in building a "windows" user interface into my XNA game, however, I'm not finding a whole lot of tutorials or code samples on how best to do this. I want to draw a sprite on the screen, say one that mimics a window, and allow the user to drag it around the screen and resize it when they are on the borders.

I'm doing a Game Development degree and have to choose a development framework to use for my next project. The two main choices I narrowed it down to are Quake III and XNA. I guess you would gravitate toward XNA but I notic

So what happens to this so called "YouTube of games" if the restrictions imply that we can't share them.
