I think I can manage a valid argument as to why it's unfair. What if Assassin's Creed Unity or The Division came out for both consoles and then suddenly Xbox got exclusive missions, cooperative missions, and stuff to customize your character for both games completely free and PlayStation had to wait a full year before they got it? They would be pretty pissed off especially if they've been looking forward to the game for literally over a year and have absolutely loved all of the franchise's previous games. That's what this is like for Xbox owners.
