Microsoft’s announcement yesterday of the free XNA Game Studio Express will bring about huge changes in XBox game development. Now, any teen with time to spare (ummm…that would be all of them) can create games for the XBox.

It’s unlikely we will see games with the detail and quality that million-dollar development budgets can bring about, but the difference will be made-up in creativity. While the established game developers focus on the high-end gaming experience, expect to see a wave of engaging, if not as visually/aurally immersive, games flood the net.
