I'm sure as heck in no rush to get to hold all the things together to create my own game but if I ever do? I have thought about basing one off the free town of Fredericia, Denmark -- which historically had freedom of religion and asylum for any crime committed anywhere else since 1650. The result was a Wild West-like chaotic border town-feel, with half a dozen religious denominations and factions struggling for survival, hitmen and kidnappers from elsewhere hunting wanted men who in turn dared not step outside the city gates, a large military garrison constantly feuding with local land owners, and a plethora of absolutely over the top personalities and stories -- and it's all very well documented.
Then add, oh, and by the way, the magic of folklore of superstition is real, shake, and bake.
