XNA Game Studio went gold today. This is a set of tools that lets you develop games on your PC and play them (or other people’s games) on your Xbox 360.
The tools are free, but to load the games onto your 360 you need a “Creator’s Club” membership ($99/year).
I’ve been really looking forward to this. I played around with the beta and now the real deal is here.
