EA really want Origin to work, Battlefield 3 was good enough to swing millions of players into the arms of EA's latest digital distribution service, and now their latest RPG, Mass Effect 3 joins the ranks. BioWare have confirmed Mass Effect 3 will not be made available on Steam, and that on the PC, it will require an Origin install for all versions.

BioWare's community manager, Chris Priestly, said on the company's official forums:

Origin is required for the PC versions of Mass Effect 3, both physical and digital. 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 ability to connect directly with our consumers.

Priestly also tackled the whole "Origin is spyware, zomg" debate, saying:

Origin is not spyware, and does not use or install spyware on user's machines. In order to allow Origin to install games and their patches for everyone to use, Origin implements a permission change that results in Windows, not Origin, reviewing the filenames in the ProgramData/Origin folder.
