Speaking to Shacknews, Brad Wardell says:
"I started out as a big Games for Windows Live advocate. I intended for Elemental to be on Games for Windows Live, but then as we got closer, the Xbox group took it over more and more. And they have things where, oh, if you want to use Games for Windows Live to update your game, you have to go through [their] certification. And if you do it more than X number of times, you have to pay money. It's like, "My friends, you can't do that on the PC." ... If Games for Windows Live maintains that strategy and they take over, I'm done. I'm not making PC games. I would be done."
I hereby declare this slagging thread for GFWL open!
