There is also Doom (2016) which (mostly) honours the simplicity of play found in Doom and Quake, but I found the mostly arena-style action rather dull and repetitive after a while. I missed the tunnels and so on in original games. Personally I'm now into modern games like the Dishonored series or Prey (2017), which a great mix of story, puzzle solving and action.

doom 2016 is a great game but it is fundamentally different from classic doom. the biggest difference being resources earned by glory kills vs resource management coming from level design.

I can recomment HROT, it is still in development but you can try the demo on Steam. It is awesome. Fun fact: it looks like Quake engine but not, it is written in Pascal.

Uh, that's more “Ok, Millenial” isn't it? I mean, I'm from the latter half of Gen X, and I miss the late-80s/early-90s era of sims.

apparently ,'xennials' are a thing now

I can recommend Civie11's YouTube channel for well-edited, amusing videos which review FPS games. In particular, his review of Doom II is excellent. https://www.youtube.com/c/Civvie11/videos

Dusk is honestly amazing. It has great movement/weapons/levels and at times does horror better than most horror games.

OK Xenial, leave Deus Ex off your list.
