Joystiq.com article Update: A Bethesda spokesperson has contacted Joystiq with clarification regarding the recent update. "We have not removed GFWL from the game," the spokesperson stated. "The only that that has changed is that Steam has removed the need to activate the GFWL codes when purchasing the game."
This only pertains to the Fallout 3 version on Steam, any other version is unaffected.
Dual DRM serves no one, so good news for all Steam cultists.
