George Lucas disagrees with you:
Further, in an August 2005 interview in Starlog magazine:
STARLOG: "The Star Wars Universe is so large and diverse. Do you ever find yourself confused by the subsidiary material that's in the novels, comics, and other offshoots?"
LUCAS: "I don't read that stuff. I haven't read any of the novels. I don't know anything about that world. That's a different world than my world. But I do try to keep it consistent. The way I do it now is they have a Star Wars Encyclopedia. So if I come up with a name or something else, I look it up and see if it has already been used. When I said [other people] could make their own Star Wars stories, we decided that, like Star Trek, we would have two universes: My universe and then this other one. They try to make their universe as consistent with mine as possible, but obviously they get enthusiastic and want to go off in other directions."
Lucas' statements in Starlog were commented on in a December 7, 2005 post on the starwars.com forums by Leland Chee, who maintains Lucas Licensing's continuity database:
CHEE: "GL is certainly not bound by the EU, though he's certainly open to using things created in it (Aayla Secura and the Coruscant name, for example). On the other hand, the quote you provide makes it sound like the EU is separate from George's vision of the Star Wars universe. It is not. The EU must follow certain tenets set by George through the films and other guidelines that he provides outside of the films."
Also:
During ShoWest 2008, Lucas gave an interview where he mentioned the difference between "his world", "the licensing world" and the "fans' world":
Interviewer: "Do you think you'd have other people continue the Star Wars saga past Episode VI or turn some of the other material into films?"
Lucas: "But there's no story past Episode VI, there's just no story. It's a certain story about Anakin Skywalker and once Anakin Skywalker dies, that's kind of the end of the story. There is no story about Luke Skywalker, I mean apart from the books. But there's three worlds: There's my world that I made up, there's the licensing world that's the books, the comics, all that kind of stuff, the games, which is their world, and then there's the fans' world, which is also very rich in imagination, but they don't always mesh. All I'm in charge of is my world. I can't be in charge of those other people's world, because I can't keep up with it."
and finally:
Another noteworthy exchange between Lucas and an interviewer appeared in the May 2008 edition of Total Film magazine:
TOTAL FILM: "The Star Wars universe has expanded far beyond the movies. How much leeway do the game makers and novel writers have?"
LUCAS: "They have their own kind of world. There's three pillars of Star Wars. I'll probably get in trouble for this but it's OK! There's three pillars: the father, the son and the holy ghost. I'm the father, Howard Roffman [president of Lucas Licensing] is the son and the holy ghost is the fans, this kind of ethereal world of people coming up with all kinds of different ideas and histories. Now these three different pillars don't always match, but the movies and TV shows are all under my control and they are consistent within themselves. Howard tries to be consistent but sometimes he goes off on tangents and it's hard to hold him back. He once said to me that there are two Star Trek universes: there's the TV show and then there's all the spin-offs. He said that these were completely different and didn't have anything to do with each other. So I said, "OK, go ahead." In the early days I told them that they couldn't do anything about how Darth Vader was born, for obvious reasons, but otherwise I pretty much let them do whatever they wanted. They created this whole amazing universe that goes on for millions of years!"
TOTAL FILM: "Are you happy for new Star Wars tales to be told after you're gone?"
LUCAS: "I've left pretty explicit instructions for there not to be any more features. There will definitely be no Episodes VII-IX. That's because there isn't any story. I mean, I never thought of anything. And now there have been novels about the events after Episode VI, which isn't at all what I would have done with it. The Star Wars story is really the tragedy of Darth Vader. That is the story. Once Vader dies, he doesn't come back to life, the Emperor doesn't get cloned and Luke doesn't get married..."
