I'll refer one that I don't see mentioned very often, that is my favorite business simulation game: Capitalism / Capitalism Lab (latest version). It has been around for about 25 years, the author keeps working on the concept.
This is a really amazing sim, and I'm surprised how under-the-radar it is. It's kind of Dwarf-Fortress-esque in how it has this slightly antiquated presentation, but hiding behind it is an incredibly deep sim, where the author keeps on adding new features.
