I have to say this is quite disappointing, but that I can also understand there stance on this. As a PC and PS4 gamer i think the best thing sony can do is allow an early access system, but only allow sony approved early access game to be put on the system. In the case of Ark however, the game is very much playable with a playerbase in the millions, and with it being out on xbox with over 1.5 million players there they must be doing something right.
