Linux Mint Xfce

Mint because it doesn't break often and usually fixes are simple enough, and Xfce because, though I don't know how well it fares compared to others nowadays, it was the variant that would run the lightest in a previous computer I had some years ago, so I grew attached to it.

Also besides Steam, Heroic (for GOG, EGS and Amazon Prime) and Mitch (for Itchio) work fine on it.
