Oxenfree and Hollow Knight are two of my favourite “current” games. Can’t wait for Oxenfree 2: Lost Signals to come out in a month or so…
Though Oblivion, Skyrim, and Borderlands 2 might be the ones with the most playtime.
Nethack variants like Unnethack, Slash’EM and Dynahack are a perennial favourite on any OS since Hack on MS-DOS in the 80s and Nethack on the Amiga in the 90s.
Oddly enough I no longer have that issue since the update (although it seems to come and go, and be present in the beta but not the ““stable”” client or vice versa). Plasma/Kwin Wayland scaled to 200% on UHD.
