will it play bloodborne, driveclub, tlou, uncharted, god of war, gt?
no? so whats the point?
No, but will your PS4 play Divinity: Original Sin, Pillars of Torrment, Cities Skylines, or Civilization V.
Can you run Mario Kart 8, Super Mario 3D World, or Xenoblade X on an XB1? No
What about running Forza Motorsport 5 or Killer Instinct on an Wii U.
I hope I have thoroughly demonstrated why using exclusive lists to defend a specific hardware platform is ultimately pointless and a waste of time. Every fucking platform has it's exclusives.
However the real important thing to question is are you in this hobby because of that company name attached to your console or because of the game library that provides you entertainment?
Anyways, yes it IS possible to build a $300 PC that will offer performance as a PS4. However over the life of the console which will have subsequently more and more demanding games releasing over top. The $300 PC running early multiplatform ports, yes I can see this. However that same $300 PC running late-into-console life multiplatform ports is entirely up in the air.
It's one thing doesn't seem to change is the slow and incremental increases of the minimum requirements on PC versions of multiplatform titles. It doesn't help that by the time we reach the end of the PS4's life the games it has that are released on PC the minimum requirements listed oddly exceed that of what the PS4 should be capable of.
But running the games isn't impossible. One is always able to lower the settings, or use a smaller resolution, or use vsync, It's not ideal, but for those who scrape the bottom of the barrel in building the least expensive PC that is able enough to run games, then it that what going to be done. At this point you are sacrificing visual fidelity for the sake of playing the game at a reasonable speed.
Nothing wrong with that, I personally just don't see this as ideal, but that is great thing about choices, is that there is always an option available.
