I think one good thing out of this is publishers hopefully don't do any more exclusives like this, either side. I really enjoyed RoTR and I'd put it in my top 3 games of the year, easy, but it makes me sad that the devs probably won't get the acclaim they deserve because of stupid marketing/business decisions.
I can't imagine any scenario where they wouldn't have been better off (1) x-platform simul release, (2) maybe pushing the date back to late jan or february. Heck, Valentines Day would have been an AMAZING day to release this game. I didn't really see that much microsoft promo of TR, and don't know a single person who really thought they need to go buy an xbox one to play the game now. Tons of people bought xbox ones, but I think all the fabulous deals were the incentive, not this game.
