Despite the fact that Electronic Arts has its own digital store, the publisher has now decided to expand its relationship with Valve Software. EA has brought many of Valve's titles to retail, but now EA is providing some of its blockbusters for digital release on Valve's popular Steam digital delivery platform.

Valve confirmed today that Spore, Spore Creepy & Cute Parts Pack, Warhammer Online: Age of Reckoning, Mass Effect, Need for Speed Undercover and FIFA Manager 2009 are now available to gamers in North America via Steam. Furthermore, in the "coming weeks," Mirror's Edge, Command & Conquer Red Alert 3, and Dead Space will also be added to EA's catalog on Steam.

"EA is one of the industry's largest publishers," said Gabe Newell, co-founder and president of Valve. "The EA titles coming to Steam this holiday include some this year's top PC titles."

"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.
