The problem with Wine is that you most know what libraries to add, etc. PlayOnLinux automates that process somewhat but still very manual.

Steam Proton makes the whole process painless, you only select which Proton version to run, and that info can be obtained from ProtonDB if you encountered any issue, it is beautiful.

As for Linux, even emulators works like never before. I could never get PS4 emulator to work on Windows, I got PS4, X360, GameCube, and a bunch of other emulators running on Linux like I couldn't believe it.

You can do the same from within SteamOS itself, you just install an app, select the emulator and you ready which is far easier than me doing this from from Linux.

Oh no argument on any of that. Valve has done a superb job at making Linux 100x more approachable and easy to use.

I just want to give credit where credit is due, because a lot of this wouldn’t be possible without the hard work of the Wine people. “Shoulders of giants” and whatnot.
