Just a few comments on some of the points raised by earier posters:
AoO's are back - I say "Yay" also. The first time one of my players heard there were no AoO's and that you could NOT fire a blaster within the threat range, his first thought was, "What the Heck???"
d20 having no variation between personal-scale and starship scale - Actually, the EXACT thing could be said about d6 scaling systems. When the WEG Star Wars 2E book came out, it had the die caps solution to different scales, which worked fairly well, though you occastionally had some off situations. When they then changed in the revised book to just dice scaling, it became strangely easy for a high-dice Jedi using a force point to cleave through a capital ship like butter. I know - because Oncarou na Gabriel (PC in our game) managed to do so once.
d6 Having more of the Star Wars "feel" - I admit, unfortunately, that I agree with this statement. Being able to do multiple actions was fun, and the fairly loose rules really made people inspire to do "Star Wars"-like actions, such as pilot a ship through an asteroid field, WHILE firing a blaster at a cockpit intruder to hold him off, JUST SO you can simultaneously repair a navigation circuit in the control panel beneath your pilot's seat...
Not including "Bounty Hunter, Starship Ace" at First level - In all sincerity - these things are the very Definition of Prestige classes. Not every bounty hunter is worthy of the name at first. This thing I did despise in the WEG game - why SHOULD every bounty hunter start as worthy of the title - Boba Fett did not start life as a bounty hunter - Boba Fett had childhood, then grew into a stalker of men for money, and took time to build the skills that would make him a Bounty Hunter, worthy of the title.
Personnally, I would have made Jedi Knight and Jedi Master Prestige classes as well - each one taking 5 levels to fulfill, and adding special powers as you went. Every force user of the Jedi Tradition would be a Guardian or Counselor, and they could stay a "padawan" their whole lives, or they could aspire to be a Knight or Master.
Prestige classes for these things give someone something to aspire to. In truth, why couldn't a Scout or Fringer or soldier become a Bounty Hunter or a Ace fighter pilot - or Claim to be, and then they manage to grow into the job.
Starship Combat in d20 is inferior - In truth, people have been claiming this since Star Wars d20 hit the scene, and I agree. A game like Star Wars absolutely needs a good starship combat system - otherwise, what's the darned point trying to make a Starship Ace? In my experience, making a scene like the Death Star trench run is rather sterile in the d20 system right now. IMHO the very first WEG Star Wars edition had the best, loosest, simplified and fast-moving and fun system to date.
I eagerly await the changes in the Star Wars d20 edition.
