The term “creator” is growing on me in the sense that it means an author who created a very vast and intricate world. I have to give credit to their imagination.
Off the top of my head would be Roddenberry, Tolkien, the Game of Thrones author, the Harry Potter author, admittedly George Lucas. I would put in Stacynski for Babylon 5 work but he admitted to borrowing from Tolkien. Eh, put him in too.
Who else? Feel free to get into comics and expand this listing.
