How does everyone feel about immersive simulation games? Anyone have any sim recommendations that aren't Arkane?

The System Shock remake thread got me thinking about it. I've played the crap out of the Dishonored series, and Prey, along with some Deathloop, and I really enjoy all of them. It's crazy how much fun it can be to just really get into it, I drop the lights and everything, sit 8 inches from my 4k monitor (ghetto VR basically), and just 'enter' the game. This is especially fun when a little THC is involved!

Any games I may have overlooked? I do prefer the First Person type games, the visuals are part of the immersion for me personally.
