Johnathanamz: All that is left is Nintendo and I think even Nintendo will port their video games to the PC in the next fifteen years.
SargonAelther: I would say it's far more likely that both Xbox and PlayStation consoles will die (and get replaced by Phones, PC and Streaming), while Nintendo will carry on with consoles and exclusives, than it is for Nintendo to release their games for PC.
According to this revenue-report... in which Sony is with nearly 3 times more revenue vs. Nintendos gaming business, we still are far away from Nintendos "total game console-dominance". However... a major part of Sony`s and as well MS`s gaming revenue is nowadays multi-platform... so, including PCs and whatelse.
Or in other words: Yes, Sony is, apart from Steam (on PC), the probably biggest "single player" in the game industry, which is as well the main reason someone like AMD want to work together with Sony on hardware/software-development. It will give AMD access to many software and even hardware-support.
There are now close to 95 million PS5 consoles sold and this value is still going up, so the console demand and development is still alive and healthy.
Despite the fact that the hardware industry was a big nuisance toward Sony on many occasions during the time of the PS5 era: In the beginning the issue with the
Minning-PCs and a big GPU and hardware shortage... and
now the big RAM and SSD shortage because of AI/Datacenter-industries, so the PS5 is produced during a difficult era in which hardware in general is not cheap.
https://en.wikipedia.org/wiki/List_of_largest_video_game_companies_by_revenue Your views are clearly through the glasses of true-PC lovers and this is fine, although it is surely no ultimate truth.
Oh and GOG is below 100 million revenue, so it is not even top 85, sadly. It is a "niche-platform" if it comes to the revenue.
GOG is perhaps around 50 million revenue, but with some more success it may slowly grow toward 100 million. The predictions are not bad because GOG was never owning a library that big and with many quality-games, they simply need to improve on many spots and yes... including Linux-support.
Anyway, sure, Nintendo remains "powerful" and with many lawyers, so i would not upset them else it will cause troubles to anyone doing it.
