I used to enjoy arena shooters waaay back in the day when Quake III Arena and later Quake Live had a still somewhat active playerbase so I could just randomly find games. No multiplayer games caught me since then.

Nowadays it's ARPGs (mostly Path of Exile), but I enjoyed Vampire Survivors too so I might go for that genre again.

Also I randomly get cravings for playing Elder Scrolls games. I just started my Nth Oblivion playthrough and I did it with Morrowind last year. It will be Skyrim again next year I suppose...

Oh and I have a few hundred hours in Dwarf Fortress too. And of course I played it the way it was meant to be played. With ASCII graphics!
