Origin will be required to play Mass Effect 3 on PC confirmed by Bioware.
Bioware’s Chris Priestly revealed that physical and digital copies will require “a one time, single authorization for the single player game” and that “there is no limit to the number of installs. Playing Mass Effect 3 Multiplayer will require a constant connection.”
You’ll be able to purchase the game directly from Origin or via a few other third-party digital resellers, but not on Steam . “Steam has adopted a set of restrictive terms of service which limit how developers interact with customers to deliver patches and other downloadable content,” he writes. “We are intent on providing Mass Effect to players with the best possible experience no matter where they purchase or play their game, and are happy to partner with any download service that does not restrict our ability to connect directly with our consumers.”
Mass Effect 3 will be released on March 6th.
