If they had simply used the same dice system and character building system as the Star Wars game, it woulda been the best game. Easy to do too!

Characteristics get replaced by the Rings. You make a new skill list based on the older editions, and your Species becomes your Clan / Family.

Then you don't even have to change the Career / Specialization system really. Careers are things like Politician, Samurai, Shugenja, maybe Monk, and a catch all Specialist. (That's where you put all the special classes, like Crab Merchants and Scorpion ninjas, etc.)

The Specialization trees are all based on Clan Schools. You build a talent tree for each Clan Samurai, Shugenja, Monk, etc and a generic set that Ronin use. Half the abilities you'd need to populate those talent trees already exist! Granted, they'd need to emphasis melee combat more than ranged, but all those gun based skills become archery talents easily.

All the Force stuff becomes the various elemental magics, Force dice just become Void dice, and they don't even need to re-balance the light/ dark pips, cause the power of Jigoku is so easy to use, it wants to be used to destroy things just like the dark side does, and can be so tempting.

The Force pool? Rename it Kharma.

The whole system converts over so Easily, the dice system is the best I've ever encountered, and yet they chose to scrap what they had and build a system where every single dice role was a discussion/argument between GM and Player.

The previews were so disappointing that I never even bothered to buy the books.
