Those of you who play Dwarf Fortress might be interested in the Incubus/Succubus/Advanced Anatomy Mod. It’s a bit silly, perhaps, but this is what it adds:

  • “Lesser” incubi/succubi that may be used as a kind of livestock. Yes, succubi may be milked (and given that this is DF, you can then create succubus cheese).
  • “Uplifted” incubi/succubi as a playable civilization, or just to make your world histories more interesting.
  • The return of tentacle demons.
  • “NSFW Advanced Anatomy”, including genitals, breasts and buttocks. You can easily mod existing creatures to have the new “parts”, but only the new creatures have them by default.
  • Hilarious combat messages like “The incubus cockslaps the human in the right shoulder! Incubus semen is injected!”.

I’m sure you’ll be able to figure out if this is your thing or not!
