Fallout is a Retro Future [url]https://en.wikipedia.org/wiki/Retrofuturism[/url] Based upon how the 1950's Era saw it. And personally it's my favorite genre. I've done some world building in the Fallout Universe creating an entirely new setting in Alaska, where Fallout and Fantasy themes are present. It's still the Fallout world but the fantasy elements are references to myths and lore, creatures and peoples who believe in legends centuries old. But legends that don't actually exist.

And some other creatures I've made were created with mythological creatures in mind. There are also swords and bows, but these are more for self defense against animals than humans.
