Playing favorites how? EA Access was offered to both Sony and MS, MS accepted and Sony didn't. Or is the PC market that is doing so?
Regardless, I don't see the big deal. Its a few days for people to try the game. They don't have some silly "Day One Edition".
Have you read the EA Access rage topics? Apparently, BioWare/EA and Microsoft are all the devil for denying the masses the demo they KNOW they would have gotten otherwise (despite BioWare stating they weren't interested in the extra work of doing a demo for DAI). 
Whatever. If I didn't have an X1, I would be mildly disappointed not to play DAI until release, but it's no different than watching all the preview vids and seeing reviewers with their copies. They get to play the game early and I don't....that's life, right?
