I've always thought that the story surrounding these two towns was greatly under-developed and thought it should be expanded. I've found multiple mods that expand on architecture of Big Town but did any mod try to adress the greater picture of both towns?

I'm not a modder but I am a writer who used to spend a lot of time role playing and writing fan fiction pieces. I have quite a few ideas for Fallout fan fiction but I promised myself I wouldn't invest my time and effort into something that I can't publish as original work (and there's no trace of sanctioned fiction for Fallout like it can be found for the Star Wars universe). However, I would be interested in contributing the lore and backstory, possibly quest content for Fallout mods. I'm also interested in talking about other mod ideas that need a story-teller's touch.

In case of Big Town and Little lamplight I think what is needed is not expansion but something opposite.
