What's the point, OP? Is it really that important for you to claim something as an exclusive? A game that is released on PC and Xbox One, and you want to say it's an exclusive game? I really want to get inside your head and figure out why you posted this thread.
Is it a personal victory for you when you are able to call a game an exclusive? Is it only Xbox games that give you this feeling? Can you please reply? What does it feel like?
