I can't abide the wacky dice, and I've heard a lot of bad things about the mechanics.
I was sort of interested in the original one for this set (Edge of the Empire?), mostly for the lack of jedi (whose mechanics have pretty much wrecked every Star Wars rpg so far).
Or in the case of one of the d20 versions, they bizarrely have to kill themselves (draining vitality points) to use force powers which seemed odd and inappropriate.
But anyway, after looking at the classes and getting good analysis of the mechanics, I decided I'd pass.
