Here's something that came to me the other day: considering in ANH Tarkin doesn't go after an actual threat (pirates, thugs, an actual military threat) but a peaceful world with no weapons JUST for the sake of demoralizing Princess Leia (well... it was her homeworld), would it be conceivable that it was Alderaan's destruction that really got the Rebellion going and (with Adobe and other FX programs) write "Remember Alderaan" on the side of some of the larger ships in the JEDI battle?
On a side note, I would like to see the confrontation with Jar-Jarrod and the Emperor's guards included in the JEDI:R edit (maybe alter the hallways to look more like the 1st Death Star, or at least longer and better detailed as what stands looks a bit set-ish), if for no other reason that just to show the guards actually DO something (and show some menace.. much less that even Vader respects them).
