If Sony wants to go full on 3rd party, then they should just release their games on PC day 1, and be done with it. They way they are going about it now is a slap in the face to both PC and PS5 users. It used to be that you would buy a console knowing that it's worth it, because all the exclusives would stay exclusive for the entire generation. But now that we know Sony is planning on releasing their exclusive content to PC, buying a PS5 isn't worth it. Now, the obvious solution to this is to just stick to PC gaming. After all, only a fool would buy a console that lacks exclusive content, or a functionality that sets it apart from a PC (Switch's portability for example). But Sony wants to go ahead and charge nearly full price for their three year old games on PC (See Horizon Zero Dawn's $50 price tag).
Well, I'm not going to pay full price for a digital version of a three year old game. Sure, I've payed $60 double dipping on Bayo 2, and Tropical Freeze. But I already had the Wii U versions of those games, which I sold to cover 1/3rd of the $60 price tag. Also those are physical games, that go into my collection and have a monetary worth to them. Digital games have no real world monetary value.
So I guess, I'll just be throwing Sony's games on my Steam wishlist, and then playing the ultra-long waiting game for them to be discounted at $50% off. Anything else is just giving in to their greed.
