There are no exclusives on PC. If you buy an Nvidia GPU, you don't get any exclusives, same with AMD. There are no exclusives for Intel or AMD CPUs. It wasn't always like that. When 3Dfx cards first launched, they had exclusive games because their glide games only worked on their GPUs. PC gamers are adults so they hated that and bought Nvidia GPUs of the day. I remember the Riva 128 cards that had two major advantages, one they were 2d and 3d cards in one. Second, they used Microsoft's directx api. Very quickly they killed off the anti consumer 3DFX 3D cards and Nvidia then purchased the company 3DFX and now Nvidia is anti consumer compared to AMD but that's another story.
I understand why they exist in the console space but why do gamers want this? Just to claim ownage on social media?
In an ideal world, you would play any game on the platform of your choice, be it PC, Playstation, Xbox or PC. Also Switch if it can handle the port.
I have a solution, what if there was a console "tax" of sorts for first part games of another company. For example, if you want to play Sony or Nintendo first party games on your Xbox or PC, you have to pay $30 on top of the MSRP. Or if you want to play a Microsoft first party game on Playstation, or Switch, again $30 "first party tax" over the MSRP. This first party tax would only apply let's say for the first year or 6 months then it would go away.
This way you wouldn't force a gamer to buy a console they don't really want just to play one or two games and the companies such as Sony and Nintendo would still offer an incentive to buy their console because you save on the first party games by not paying that tax.
