Dwarf fortress is very complex but it’s also very chill. You can spend a lot of time reading, but you don’t have to read every single little detail. Grimrock is old school style dungeon crawl which is a lot of fun, I haven’t played it very much myself! There is two in the series iirc.
How about: Stardew Valley, Dwarf Fortress, Legends of Grimrock or Rift Wizard? Vastly different genres though.
Dota. Fuck that game! Other than that, WoW, Rust and Arma3/DayZ.
