^ If we are not using the EU canon as a basis then all bets are off, of course. I was just trying to relate what the Star Wars universe looked like in its past based on the sources available. The ancient jedi precursors did use swords, as me and another person pointed out. My issue is the Jedi and the lightsaber are heavily associated and are the symbol of Star Wars and to not have these, or remove one from the other, could be detrimental.
Detrimental to whom or what?
I think I've found the main point of disagreement between us: You believe that, as fiction, the Star Wars story can be ret-conned, re-imagined, or re-written at any time. It is, after all, just a made up story that anyone could alter if they really wanted to. I think there is an internal continuity to all fictional stories and since the only source for that continuity I have is the EU I stick to it unless it in contradicted on screen. YMMV.
Actually, I don't think that's our main point of disagreement. I think the main point of our disagreement is whether or not you could tell a story set in a pre-light saber world and it still be Star Wars. Or a pre FTL.
And I think you can. I don't think it would be a story that would appeal to the masses, but then 99% of all the Star Wars material out there (books, comics, computer games, wookiepedia, etc) doesn't appeal to the masses either, and hasn't been seen.
But, I do think it would appeal to the Star Wars fanbase who DO read the novels.
I agree with you that the Jedi and the lightsaber are heavily associated with Star Wars. But, I disagree that it's a limitation to a story.
Why can't you tell a story about the Jedi pre-lightsaber? I don't understand why you can't. It's a Jedi with force push, force speed, who has a sword because light sabers haven't been invented yet. A story of long ago, longer ago than Episode I.
I do think it is all fictional and can be rewritten (with in reason, not like making Luke and Leia lovers, that would be absurd.

). But, my point is, just because there HASN'T been a story set in a time before a lot of technological innovation doesn't mean there CAN'T be.
Hell, make it the story of how the light saber came to be...
The technological stagnation of the Star Wars universe does sorta irk me. And I feel like all of the tech is there is say SEE THIS IS STAR WARS. But, to me, it's window dressing, not the substance.
To me, the substance is a fight between good and evil, whereas Star Trek, is more about exploration and IDIC.
