Fading Suns d20. It has all of the setting goodness of the original, and ditches those annoying "personality attributes" (Faith, Passion, and so on).
And from a d20 rules point of view, it has classes for nobles, non-spellcasting priests, and merchants that can stand eye-to-eye with the other PC classes, instead of being weak NPC classes. It's great to see classes that focus on social powers, instead of physical or mystical ones!
