I don't use my computers for modern gaming. Like OP, I prefer tabletop games, though I do speed run crossword puzzles and play some PixelDungeon on my phone when I have spare time. I also built a Retropie, and play some old Atari and PS2 roms on a bored Sunday. My stuff can run Civ IV, which is probably the last title I bought.
My main systems are for work, or for supporting self-hosted services including local infrastructure, home lab stuff, email, blogs, home automation, media servers, etc, etc. Lately I've been getting into SDR projects using RPi or old laptops.
So, uh... Yeah. Fun stuff, but not so much gaming.
And we all get a share!
