My friend is using Edge of the Empire as a base for a Call of Cthulhu conversion and it got me thinking about what FF might do with L5R, what with the Christmas in July sale, and i had a thought that Force and Destiny actually has almost all the mechanics you'd need for a pretty decent L5R conversion. You'd want to splash in some of the political stuff from Age of Rebellion, but hear me out:
The high level thinking is: Careers map basically into Clans, and Specializations into Families. The mechanic for double dipping into specializations even works here. Force powers provide the framework for a somewhat less blastery version of shugenja, and the dark side mechanic gives you a framework for taint (though this would need a big of work). The lightsaber mechanics built into the various specializations are a good start on classic l5r duels, but theres some work to do there too. Probably the biggest mechanical difference here is that the stats don't link to the careers, instead careers and specs focus on skills, and skills associate to stats. i think theres an argument to be made that by jimmying around the skills you can make the ring associations though.
to me the biggest strength of fantasy flight's star wars system is the advantage/threat mechanic, which augment success and failure and can be used both mechanically and narratively by both the players or the GM. This makes for some great scenes and i think it would really lend itself well to L5R, where things often aren't purely black or white when it comes to task resolution. particularly in courtly situations i think this mechanic would be solid gold.
anyway, this is just kind of a larky thought, i don't know if i'll end up putting the effort into doing it, i just thought it was an interesting thing to think about. for all i know theres another thread on here i wasn't able to dig up that had the same idea.
