When is an idea for a story or a universe considered (or should be considered) to be stolen. I have an idea for a story that is heavily influenced by other IP and authors. A specific example would be an idea for a sci-fi story following a human scientist to experience and study the interactions of soldiers who are in fact clones of each other in the field (battlefield, off-duty etc.) Now obviously there are huge parallels from the above story and many things in the star wars: clone wars cannon. The above idea isn't my actual idea but its an old idea I had and a one that I thought was well thought out, but I dropped it because of the likeness. This happens with a lot of my writing ideas, I don't think i'm alone but is this because I just don't have good ideas, or is my creative process flat? also, do you guys consider it stealing?
