Ideally Further Adventures of Luke Skywalker should have been done by 1992-3 at the latest, the same with Indiana Jones unfortunately.

Obviously if star wars VII had been made then the Zahn Trilogy would not have been allowed to be written.

Age is a factor not just for the cast but the directors as well.

Would Lucas have come out of retirement sooner for SW 7 or Spielberg when he wanted to be taken Seriously as a director want to do INDY pictures?

We know they wanted to do other things.

And Harrison Ford was a big star outside star wars and indy he did not need them.

Lucas had decided by about 1991 to not make the sequel trilogy. It just was not a completely closed off option until he made the decision during or after making the prequels.

He only sort of changed his mind because he does not have to write or direct the new movies.

Are 7-9 G canon or Disney Canon,lol.
