The two subnautica games are pretty good vanilla but I always end up adding the "snap to" mod for building and of course a map! When I want to just do base building the mod that expands your inventory is invaluable too. Lets just build and hold the resources you need instead of having to go back and forth.
Valheim I honestly don't think I've played the vanilla version. Theres just so many good content mods and qol fixes that I can't imagine playing it without
Assuming you're asking from a place of wanting to know. "Dwarf" is a term that has been used in the past to describe little people or those suffering from dwarfism. It can be a negative word for some in that community and is tied to ableism in that way
