I have been trying to start writing for a long time, but every idea I get either is first inspired by, or sometimes, directly related to, things I've seen before. I mean I've had ideas that take place in the Star Wars universe, and Wing Commander, and Vampire: The Masquerade (or vampires, in general), etc. My wife makes fun of me, and says I can't come up with an original idea. So, at what point is a previous concept original, or is there such a thing? For example, is it possible to write a story that has vampires in it (or robots, space travel, etc.) without it being a rip-off of an already-published story? Thanks for any help you can offer.
