On ripping off Tolkien; In 1949, Joseph Campbell wrote The Hero With A Thousand Faces. And in it he explained how often there is a formula to writing that people fall into. So many authors were inspired by Tolkien, they weren't trying to rip him off. Though Terry Brooks was close. Tolkien had great worldbuilding and an epic journey so anywhere you see those two close together with fantasy, people say that it's Tolkien-esque. And it's true to a point. Fantasy is usually about a quest in an imaginary world.
Here's The Hero's Journey, see if you can put Tolkien and Star Wars neatly in it.
