"Gaming" seemed the best fit for this thread since I didn't see a "Hallelujah" section...
Games for Windows Live will be discontinued on July 1, 2014. Although it is available through Steam, Age of Empires Online requires features of the Games for Windows Live service. You can continue to enjoy all the features of Age of Empires Online as the service will remain 100% operational until July 1, 2014 when the server will shut down.
With GFWL being replaced by Steamworks in Batman: Arkham Origins (see here) and the Windows Live Marketplace shutting down in three days (see here), I knew it was only a matter of time for GFWL to see its demise!
Still nearly a year away, but at least that means it's pretty much a given that no new games will feature it!!!!
