Those hoping to play Mass Effect 3 on Steam will be sadly disappointed to hear that Electronic Arts will be requiring the use of Origin for PC players to play Mass Effect 3 at launch. The game will require both physical and digital versions of Mass Effect 3 to have a constant connection to Origin in the form of a one time single authorization for the single player game.

The constant connection to Origin will be required for those playing the multiplayer portion of the game. Here is the reason EA has given as to why it is preventing its games from releasing on Steam.

During initial release Mass Effect 3 will be available on Origin and a number of other 3rd party digital retailers, but not on Steam at this time. Steam has adopted a set of restrictive terms of service which limit how developers interact with customers to deliver patches and other downloadable content. 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 abilityto connect directly with our consumers.

Mass Effect 3 will be releasing on PlayStation 3, Xbox 360 and PC on March 6.
