You also forget the SW universe IS technically in OUR universe which is also where the halo universe is. Not to mention the millions of jedi from the old republic to the new era AND the hundreds of SITH (each sith is considerably more powerful than each jedi) Also better sensors in SWU and travel AND there are cloaking device in SWU that STILL fool their highest tech sensors. 1 star destroyer is armed up enough to LEVEL TO THE GROUND an ENTIRE planet BY IT SELF. And there are a few 100k of them. Stuff like that.
