It makes it difficult to support a game when the makers limit half their player base. The end result is that the game will suffer, and we will all lose out in the long term. Why would players spend money on a game that actively limits them? No one likes exclusives - they are just made to support a dying profit model. Yes tomb raider came to xbox a year before ps4 - but the makers of the game lost out on so much more - in the end... no one wins.
