There are my example was just explaining the Skywalker effect.We're not talking about mass market here we're talking about role playing games. And as Luiscarlo14f pointed out, some people don't want to play Star Wars because they're characters aren't the big damn heroes who get to blow up the Death Star and cut off Vader's hand. There were plenty of great stories to tell in the Star Wars universe for characters who aren't Luke, Leia, or Han.
This isn't new you had books set in timelines well away from the Skywalker's back in the 90s. Galaxy usa big place as well and plenty of books for non Skywalker type games.
