So, I’ve been working on building a world setting for a fantasy story of mine, and their system of government (which will affect the plot but is not central to it) is loosely based on the pre-empire Roman Republic. I like the feel it’s given the story, and as such I’ve used it as a “theme” to inspire several other aspects as well. I’ve given a few Roman-sounding names to both characters and places and I’ve envisioned some of their architecture and clothing/armor to have similar style. What I’m starting to worry about now is if I have overdone it. I don’t mind people reading the story and not having any trouble recognizing what influenced me when writing it, but I don’t want it to seem like some huge rip-off either or that I was too lazy to come up with something on my own. I realize there is no hard and fast measuring stick that I can compare my story to, but does the fact that I’m even worrying about this indicate that it is a problem? I would really appreciate some advice from more experienced writers.
