Forgive me if this has been suggested before (I'm sure it has), but I can't seem to find the thread for it.
As we saw
recently, Goblins now get their own misshapen homes. Toady said he plans to give Elves large trees to
burn them alive in. We have the option in adventurer mode to be an Elf, Human, or Dwarf. Why can't we start our own Elf or Human fortress, or even Goblin or that new race we heard rumors about?
The code for a Human town should be fairly similar to dwarves, just some different happiness requirements such as the absolute need for alcohol or the lack of cave adaption. Perhaps Humans could get 'cave sickness' if they don't see the sun every few months, while Elves need the sun at least once a month. Goblins would differ in that they would kidnap new citizens as well as breed their own.
I mean, sure, there is nothing stopping us from building an above-ground city with walls and houses and just pretending it's a human town, but it'd be a nice feature to have.
