Bill Slavicsek, designer of WEG's D6 Star Wars RPG has written a book called Star Wars: Definining A Galaxy.
It retells his experiences with creating the Star Wars RPG and how he was allowed to flesh out the Star Wars Galaxy, in many ways having the RPG lore make its way into comics, novels and movies.

It Was a Dark Time for the Galaxy
In the late 1980s, Star Wars was becoming a fading memory. The movie trilogy had concluded. The comic books and novels were winding down. The action figures had run their course. As the franchise celebrated its tenth anniversary, there was a new ride at Disneyland and … not much else. Not until a small hobby game company released Star Wars: The Roleplaying Game and The Star Wars Sourcebook. And suddenly the galaxy began to expand. This is the story of how a group of dedicated fans and gaming professionals helped pave the way for the Star Wars Expanded Universe — as told by one of the original architects! This book explains how material created for roleplaying games helped shape the Star Wars universe — and continues to influence it to the current day.
I think this could be of great interest to fans of the RPG?
