Some examples I've tried that are close:
- Dwarf Fortress but the user interfaces unpleasant
- I've set up Minecraft with lots of villager and NPC mods which might be an option
- Rim World on peaceful mode with some cozy mods
- simulation based games, typically with less narrative structure
Like, I'd like to be able to kind of just explore and wander around without having to worry about a grind too much either which kind of rules out stardew Valley
