Most shit works, that said your expectations should firstly be that any windows only game doesnt work even if its not the case because the fact that its running most windows only games without major problems is really impressive, show me how to do that on windows (VM not allowed as Wine and proton arent VMs)
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.
Sure... Which is why Valve has built Proton, which makes nearly all PC games run on Linux... Sure, the developers of the games themselves should have made the Linux port, but for many developers it's cost prohibitive to support another platform with very few potential customers.
But the more players who run Linux (and Steam Deck by extension), the larger the incentive for developers to support Linux natively. And in turn more games will get made for Linux, which will draw in more people to switch to Linux.
So as long as my game runs, then I don't care whether it was the original developer, Valve or an open-source developer why wrote the code that made it work. And luckily I'm one of those people that don't mind having to tinker a bit to make things work (hence why I'm on Linux in the first place)
If we as gamers stubbornly refuse to switch to Linux until our games are natively ported, then developers might as well just develop their games for Windows, where the players are...
Funny coincidence, that game was sitting in my backlog for a while and was the first game I installed on my deck. It's impressive how beautiful they were able to make such a dark and bleak forest. And yeah, 0 problems so far.
