My two suggestions are:
- On your first week, configure a backup solution (check your distro wiki for details). Because linux is very customizable, reinstalls can be painful.
- Use flatpaks for applications, there are good store applications that simplify the process. (Some apps misbehave as a flatpak, like Steam).
I think a lot do, but as I don’t play them and most people complaint about anticheat being the heel in linux gaming…
