Troubadour
I always felt that Star Wars was more of a hybrid of fantasy and science fiction.
I try not banter about Star Wars to often, I was a Trekkie kid from the first time I heard those iconic words, "Beam me up Scottie". Don't get me wrong, I love Star Wars, but I'm also just going to be honest and say, my favorite Star Wars "movies" starred Peter Griffin! Still, seeing as it ties in so nicely to the topic of the thread, I could not agree more more with ecdavis. Star Wars always had a distinctly fantasy feel to it, more so than Sci-Fi. Which makes sense, as Lucas has openly admitted to referencing "The Hero With A Thousand Faces" by Joseph Campbell (Which on a side note is an interesting read, as is anything you can get your hands on by Campbell) as he wrote the script. Campbell's book basically expands on Adolph Bastian idea that myths from all over the world seem to be built from the same "elementary ideas." ~ see were this is going!
I myself have suffered the daunting plagiarism bug, and now I have a folder full of half finished stories that succumbed to that disease. So often I would be writing an idea, then find another book with exact same concept, after the fact! Or another really big one for me, is knowing an idea would work so well in a story, but hoarding it because I also want to use in another story idea I have brewing.
Now, before I write I always say to myself "Original is not new, it's old re-imagined and personalized."
