George Lucas loves revisionism. In a recent interview with Starwars.com, George Lucas said that as far as he was concerned, there was no Star Wars after Return of the Jedi:

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.

It's sort of an interesting psychological profile of the man, isn't it? The Expanded Universe, most of which takes place after Episode VI, largely exceeds the quality of the prequels. And if Star Wars is "all about Anakin," why did he start by focusing on Luke?
