The Stars Wars stories are not set amongst a few locations. Each film has introduced new places, thus my earlier comment regarding The Empire Strikes Back. Harry Pottery is rather focused on London and Hogwarts. Star Wars, and just the films, show Tatooine, Alderaan, Yavin IV, the first Death Star, the second Death Star, Star Destroyers (city sized ships), Super Star Destroyers, the Cloud City of Bespin, Naboo, Hoth, Dagobah, the Forest Moon of Endor, Coruscant, Geonosis, Kamino, Kashyyyk, Mustafa and (if he isn't pulling another Khan) Jakku. How many of those places have three memorable location you can name, much less a dozen or so to make something like the Wizarding World?
