Windward.
I bought that game because it is resembled table-top game we played back in USSR days, where you have to find some relatively thick paper or cardboard, or cloth, draw a map there (or even add a landscape), make a wind "roulette", and cut some ships' models from wood (and add matches or bamboo splints as masts and cardboard "sails". Believe it or not, I still have a box with those ships somewhere, LOL.:D Ah, sweet childhood memories. Anyway, Windward turned out to be almost like that game, only on PC platform, where you have nothing to do to start playing. I have no idea how I played over 150 hours in a game I thought I'll play for a couple of hours. Stopped playing only because playing solo off-line is kinda hard for raids - allied AI relatively derpy. I'm not Esoterickk (watch his Destiny 2 videos) to solo-yolo all the content.
Another title I want to mention is Assetto Corsa. I bought it during early days, when it had one car and one track, and ended up buying steering wheel with pedals and gear-shifter. Yeah, like I don't have that in my IRL car already. :D Surprisingly, this game is very enjoyable even with mouse steering and "binary" keyboard, without any ability to gently adjust throttle/brakes. Believe it or not, but I enjoy driving one car on one track (not Nordschleife, mind you) for hours without any irritation or annoyance.
I could've mention ETS2/ATS here, but they have some technical issues that prevent "nothing box" (search for "Mark Gungor" on youtube) state of of the mind.
Games that definitely earned their place here are Oxygen Not Included, Rimworld, and Factorio. First reminds me of my job (construction), where you have to work like a foreman, carefully laying out plans, placing priorities, blueprints, hoping your workers don't screw up anything (don't worry, dupes will:D). All three definitely are "Ok, I'll just check what was built there while I was away" a-a-and you spent entire night engineering stuff. *That meme about German forklift driver who returns home and plays forklift simulator.jpg*
Last but not least, are games from Amplitude Studios, precisely named "Endless". I definitely do not want to even start thinking about how much time I sunk into entire series, but more than once simple evening "wind down" turned into something similar to "binge reading nights", when you are interrupted only by that annoying noise, turned out to be your alarm clock.
¯\_(ツ)_/¯
