  I use links to threads only because they are expanding topics or many ways to do the same thing. I hope this helps.
  
  Q: Are there any tutorials?
  A: Sure there are to start do the following:
  1. If you go into C# Express -> help -> Contents
  
  2. Help program opens expand:
  XNA -> XNA Game Studio Express -> Getting Started with XNA
  
  3. Click "Your First XNA Game"
  
  Then Check out the following sites.

• 1. Q: Where are the physics?
     A: XNA is a framework to develop from similar to how .NET is a framework to develop from. You still have to role your own physics since XNA is not a Game Engine. If you would like that please check out TourquX when it comes out.
