A recently-released patch for the Steam version of Bethesda's post-apocalyptic RPG Fallout 3 suggests that its Games for Windows Live support and DRM is being removed, likely in response to the service's decline and marketplace closure.
NeoGAF reports that the update removes Fallout 3's SupportsCDKeyCopyToClipboard, ShowCDKeyOnLaunch, and legacy key registry functions -- all key components of Games for Windows Live integration. Blue's News finds that the game still installs the Games for Windows Live client upon launch, however. Uninstalling the client currently renders Fallout 3 inoperable.
Several games have ditched Games for Windows Live support in recent months, including BioShock 2, Batman: Arkham City, and Warhammer 40,000: Dawn of War 2. Several Microsoft-published PC releases and high-profile games likeDark Souls and Grand Theft Auto 4 still require Games for Windows Live to function.
