Nigga what, there are ton of PC exclusive games out there, even timed ones. Fuck man, there are even genres for the most part that are limited to the PC platform due to the flexibility of the platform, and let's not even get to the VR games that are being developed first for PC and are then ported over to Console/Oculus. Even then, PC ports can brute force there way to being the plain better experience on PC over time due to the modding scene that is on the platform.
Sony games up until 2013 debatably offer exclusives that were unique to the platform, such as SotC & ICO and Demon Souls. But now? Only Third Person action games that are sometimes open world and have stealth elements. Fuck, even Microsoft is going to have the better gaming experience on consoles due to the variety of games it's going to offer in the coming years. I used to meme on Microsoft for only having 3 game genres they fall back on, but now they have at least 5 and Sony only has 2: Third Person Games and Racing, and that's pathetic.
