One of the benefits of (a) Having something almost every amateur XNA developer wants (see my button pack), and (b) pretty good web analytics software is that you get to see where all the good XNA resources are because they link you! Thus, I have compiled a list of all worthwhile sites that I managed to find (in no particular order):
- Learn XNA
- XBOX 360 Homebrew
- XNA Resources
- Official XNA Forums @ Microsoft
- The ZBuffer
- Let's Kill Dave
- Jeff Tunnel's "Make it Big in Games"
