Thats not the point. You buy Games by Developers with limited resources. They dont care about FOSS you could say, in many cases. So you are unsupported.
Linux runs Linux Apps, its Essence is that it is a free OS, that you can trust.
Running proprietary stuff made for other Platforms is interesting but a Battle. It makes no sense you could say.
It makes Sense for Valve, as they save themselves Billions in Windows Licenses and they can make a tailored device. And they sell Games.
For you, paying for Games and then working to make them run, I dont know.
Not that I dont like the idea, but its the job of Developers to make the Games run.
