A few posts above (#248) I mentioned that you should be able to negotiate with any civ organized enough to hold multiple cities. So the other (AI) players are what you have called minor civs. It is certainly true that a lot of town/villages would survive the actual nuclear exchange, occuring on one day or a few hours. But, 20 years after, with barbs and mutants running around, I don't think there would be many town/villages left. They would have been eaten or resettled with other survivors. The goody huts you encounter, or refugees that appear in the ruins, are supposed to represent those. There is a middle category which might be interesting, which is stalled, single city civs. A while back the FFH explorable lair thread was mentioned. One of the capabilities of this mod is to have goody huts that survive and allow you to interact in several ways. It's a cool idea but hard to integrate the code with Fury Road. Several people have suggested "natural wonders" like The Glow, or a Boneyard, etc. I could certainly have a small, fixed size city as a natural wonder, so I will keep this idea on the list.
