Stellaris was actually the first "native" game i ever tried on Linux. I used the GOG Version and it worked without any issues for me. Same goes for Limbo. Switching to Linux has been a great experience for me. Personally i don't have any issues nor any game that gave me problems in the 3 years since i haved switched.
Btw you people should keep in mind that steam provided a Linux Runtime as well. To really test "native" you might switch and try "legacy runtime" which is no container (i think the way Steam handled it before - meaning native). The change has been made a few months ago. That also gave me issues on certain games while "true native" still works. See

Yeah, I have the Steam version of Stellaris, and admittedly I didn't try it until 2-3 years after the game came out. It's possible it worked better before. Stellaris is just an example.
To your point about the steam runtime, there are also examples like the
GoG version of Baldur's Gate, for which, conversely, the Steam runtime is the easiest fix to get the Linux version running at all. But there again, the Linux version is a trap--if you want access to the best mods for the game, and you want the easiest time installing them, your best bet is to install it as a Windows game and use Wine to run the game and install the mods. Just double click them as if you were on a Windows machine and Wine will take care of the rest. Ignore all of the byzantine modding guides for the Linux version of BG1; they were ok in their day, but now they're obsolete.
What I'm getting at here is that Proton/Wine may not always be the
best option, but it's probably the best default option if you want to minimize headaches. I'd say 90% of the time, if you toggle on Proton-GE, the game will just work. Of the remaining ~10%, the vast majority will be fixed after 5 minutes of browsing
ProtonDB. Once you know these things, gaming on Linux really isn't much more obvious trouble than it is on Windows, which occasionally has its own headaches. There are caveats, of course--competitive multiplayer doesn't work, for example, and performance isn't always on par versus Windows, though this is a bigger issue for Nvidia owners, and the newest shiniest features may need a extra time to percolate--but for the most part, I think the average Windows gamer would be shocked at how smooth the experience is on Linux in 2025.
And we largely have Valve to thank for that welcome development. See? I'm on topic after all, lol. Sort of.
