Star Wars has endured because so much of its worldbuilding has remained consistent over the decades. Sure, many elements have been fleshed out, like Obi-Wan’s offhand mention of the Clone Wars in A New Hope becoming the basis of the prequels and several animated series. But there’s rarely anything in later works that directly retcons the basic premise; a Jedi in a new movie has the same basic powers as a Jedi in an old one.
