Hello all! I'm new to the forums and I have a question that I hope somebody answers. Years ago I have written several urban fantasy stories. They were generally liked, and all, and recently I was thinking about translating them to English and serializing them online. I have my doubts, though. During the time I was writing it, I was under the influence of an RPG setting. It's not a fanfiction; the story is original. All the characters are original. The city in which the story happens is fictional and made up by me. There is not one copyright term used. I had, however, recieved the feedback, that it is possible to figure out what I was influenced with. Actually the authors of the feedbacks were quite aggeresive about that. I know that US copyrights are much more strict that here in Europe and I want to know if I'd fell in trouble, trying to publish it as an ebook. After all, "The Underworld" movie got sued and all the time I hear about people suing J.K.Rowling for some undefined similarity to their works (maybe they are simply trying to get attention, because they know their claims are unfounded). Does it fall under the definition of derivative work? Or it's just embarassingly unoriginal, but legal and fair game? I'm not trying to create a bestseller here, but I'd like a couple of $, or even a small publisher.
