Trackmania requires no more configuration than it does on windows, and if you use KDE, the interface is almost identical.
The only thing you’d have to learn is to install steam from the app store instead of from the internet, if you give it a shot, I don’t think you’ll find it to be as difficult as you imagine.
The full steps would be
install linux mint (if you have no preference that’s the easiest distro) > open app store > install steam > install trackmania from steam > hit play
edit: just tested it to verify, yeah, trackmania required no additional setup or anything from the standard windows version
Installing linux is a 15 minute process, the only hard part is getting a flash drive, and you only have to do it once, once you have that flash drive you can do it easily endlessly.
I highly recommend trying it out, linux is significantly easier to use and has significantly less maintenance burden. That’s why I give it to the elderly, they’ve all said it makes their lives significantly easier, and none of them have switched back.
Plus, even on a windows machine, the first thing you should do is reinstall the operating system when you get one, especially for second hand machines. Every single major manufacturer puts a bunch of garbage on the computer some of which is nearly impossible to remove without a reinstall, considering you already should do this anyway, it makes it a much easier pill to swallow.
some examples of how linux is easier:
Your computer won’t forcibly restart for updates, ever
Your computer is never doing anything in the background that you don’t ask it to do, so you don’t have to worry about if the power cuts off, whether your machine will still work.
All of the updates are centralized so you don’t have to worry about various updaters
All of the installations are centralized so you don’t have to worry about using all of the various installers windows has, making sure not to enable it installing extra crap, etc
Guaranteed no cruft that slows your machine down every time, you don’t have to go through uninstalling a bunch of crap
Centralization means unless you do something very strange you never have to deal with malware
There’s other things, but I have found that these few things make a significant difference, especially for the elderly.
I would consider it unwise to avoid learning about a machine you regularly have to interact with, you’ll only make your life more difficult in various, impossible to observe ways from the other side. I guarantee the only difficult step will be the first install.
