No one can beat Playstation as the king of gaming so the competition has to team up together. lol

I think this is more of a "MS cant handle both Sony and Nintendo so they need to team up with someone" than anything else really.
My (locked) thread about how difficulty should be a decision for the developers, not the gamers.
