I am all for exclusives; For one it enables the developer to maximize the hardware - a game designed to play on the PS3 architecture should not play the same on a different platform. First party titles also help establish the brand of a console in the same way that Sonic and Mario became synonymous with SEGA and Nintendo. Purchasing an Xbox One guarantees me that I will get a Halo title, just as a PS4 would all but guarantee I would get a God of War and Mario with the purchase of a Wii U. So in summary exclusives may not be liked by all, but it sure makes owning a particular platform fun if for nothing else uniqueness.
