EA's digital PC store Origin can activate Steam codes for some EA games.
PC Gamer successfully redeemed keys for Battlefield: Bad Company 2, Dragon Age 2, Dragon Age: Origins, Mass Effect 2, Dead Space 2 and Alice: Madness Returns. Mass Effect 1, however, did not work.
PC Gamer managed to validate the Steam product key for Dragon Age 2 on Origin, and then launch the Steam version of DA2 from the Origin client. The Steam overlay and chat functions were intact and present.
Origin already has a peek around your PC for existing EA games. Will peeking in your Steam library for EA games be the next step?
EA wants Origin to be the de facto online place to buy and download EA PC games. Origin will be the only place to digitally buy Star Wars: The Old Republic.
