Ha, Star Wars without Jedi is like Harrison Ford without Jason Dean Alt or Lem without Pirx, or the Strugatsky brothers without Rumata Estorsky.
They even released a book about the Clone Wars.
Games and other things where there isn't even a hint of Jedi.
What makes it so huge?
For example, Lem or the Strugatsky brothers are 100 times closer to me in spirit than Luke Skywalker.

Doesn't fantasy go in circles?
Ha, did they come up with new creatures?
As for science fiction, it's become "combat-oriented" - a superhero, like in Zadornov's stories, not just a big guy, but a big guy with an attic... in a fairly fantastic world, but still... bullets bounce off his forehead...
But in my opinion, there is quite a lot of good science fiction, you just need to not go to trendy stores for colorful covers, but to a library, for example, or at worst, download it online...
