The rumors were true: Electronic Arts is now officially a Steam publishing partner. In celebration of the occasion, the company has unloaded its holiday slate of titles on Steam, Valve’s popular PC-based digital distribution service. Up for grabs is Spore, Warhammer Online: Age of Reckoning, Mass Effect, Need for Speed Undercover and EA Sports FIFA Manager 2009.

“We are pleased to extend our holiday titles to gamers worldwide via Steam — a revolutionary technology that is one of the game industry’s most successful digital distribution services,” said John Pleasants, President, Global Publishing & Chief Operating Officer.

The support does not end here. Due within the coming weeks is Command & Conquer Red Alert 3, Dead Space, and the yet-to-be-released PC edition of Mirror’s Edge. I’d go as far to say that Valve has cemented its status as the leader in digital distribution: the addition of EA titles on Steam is certainly a big win, not only for Valve but also gamers everywhere.
