Just for the record, if you’re going to play Battlefield 3 on the PC, you’re going to create and use an Electronic Arts Origin account. Period. Developer DICE has confirmed what, really, shouldn’t be a surprise to anyone, a couple days ago on Twitter.
This covers retail copies on DVD, but we can assume it extends to any digital copy bought from a download service (other than, ahem, Steam) because well, why the hell wouldn’t it. This is EA’s new PC digital distribution service, it makes sense it would use its biggest selling PC title to drive people to it, like it or not.
