I am very non-technical and I have ended up with Linux Mint Cinnamon which was the first thing I tried, with Steam dealing with the few games I have played the past four years or so. It has been mostly non-Steam Fallout 4, No Man’s Sky, Baldur’s Gate 3, Guild Wars 2, and Steam version of Lord of the Rings Online. Stability varies but I think it is mostly my hardware being old.

Overall I have used Mint for maybe eight years, at first only for internet browsing. I still played LOTRO and Guild Wars 2 with my trusty (well okay, the games started to be rather crashy) WinXP around 2020. Hm… a year or two, here or there. I don’t actually remember when they started to drop support for XP. I originally tried Steam on Linux for LOTRO.

Just as a background info I’m going to be a little bit dramatic and claim that I don’t like Linux, I use it out of necessity. Even if I am generally fine with it, as far as I can manage it.
I just don’t like the command line at all. I also don’t like the program “shop” like system. I think I can see it on my current Mint as Software Manager, now that I check but I don’t want to start it. It is that I don’t like them “calling homes” or managing things which is how I see the command line and the manager being like.
I can download a Steam installer from the website and then it sets itself up, with command line type window, downloading what ever it likes from somewhere, managing things… fine, I have to deal, I want to play games. For general computer use I can download Firefox and some other Linux software from websites, they start when I click the executable and that’s the way I would like things to work way more. I do let the driver manager set graphics drivers when I make a new Mint installation as I can’t even begin to understand other options.

My favorite thing would be the possibility to easily set up a Linux computer for offline games without ever connecting it to internet.
Once, maybe 4 years ago I did somehow install wine on Debian which I think I didn’t connect to internet in the process. The one game I tested did launch but didn’t really display well because no graphics driver.
Another experiment, on Mint last year, was to install wine with command line (the horror!), I could launch the non-Steam games I installed but didn’t try playing them. I can’t remember for sure but it may be that the games just didn’t run as well as they did on Steam’s Proton on that same Mint installation. Based on when I sometimes read about Linux, wine does seem to need plenty of config which I really don’t want to do.
