Talking on the eve of its Gamefest event in Seattle, Microsoft has revealed XNA Game Studio Express, a new product which will allow indie developers and students to develop simultaneously on Xbox 360 and PC, and share their games to others in a new Xbox 360 ‘Creators Club’.
Now this is what I call a great idea! The development software will be free for Windows PCs, and it appears that you can code on the PC and immediately give it a test on the 360. Future plans include an enhanced Live Arcade section that may include these homebrew games.
