I don't think it hurts that much seeing the saber built but personally I would have had it built on Dagobah not Tatooine and have Yoda die in the beginning of the film (after completing Luke's Jedi training as best as he could) rather than just waiting for Luke to return and dropping down dead in the middle of his reunion conversation.

Yeah that was unfortunate timing as well as the numerous times Yoda says "Luke!" in that scene.

ROTJ has a slow start--ESB at least had some connection-following the probes to Hoth, but the other seemed merely to ensure we got another Star Destroyer opening.

Like there's a considerable time lapse between ESB and ROTJ--supposedly Chewie and Lando are looking for Jabba and Boba Fett--they will rendyvous on Tattooine (presumably when they locate them?). I assume that is the one place Jabba wouldnt be--unless it was just some awkward dialogue.

Would Luke rescue Han before going back to Yoda? Probably, but unless they went after Han immediately I would have expected him to go back to Yoda pretty fast.

If there is anything I would like to know more of from a historical paper trail, is what would have happened had Lucas kept the gang together (Kurtz, Mrs. Lucas, etc) through ROTJ's production. Just to get a sense of how it may have been different. I think I read Kurtz say he felt the new Death Star was repetitive--well if that is true what type of threat and location would they have had instead? The Endor base attack was rather boring--visually not exotic. If Lucas hadnt gone cheap what might that have been like?

I think i read somewhere that the Emperor's chambers might have been on a lava rock planet?

If Leia wasnt the other, how would that have played out--how would Kenobi have explained not revealing who Luke's father was..etc.

Since I dont like thinking about the prequels at all, this is what I would be curious to know more about if any paper trail exists to highlight it.
