I wasn't going to mention this because the project is still in it's infancy, but since we're talking about systems for use with Star Wars MU*s, I figured, what the heck?
I am currently involved in the construction of a Star Wars MU set during the time period of the new movies. We had originally intended to use the FFG system, but decided against it due to the complexity of the dice mechanics (and a few other reasons). SAGAs was not an option because none of us cared for D20 and D6 was just so... dated.
We ended up going with a custom system based on QuestCore. QuestCore is often described as a 'crunch lite' system aimed at fans of D20 who want simpler and better mechanics. It's simple to learn, easy to code, and works very very well for MU*s, at least IMO. I'm curious to see how well it works in actual practice, but we have a lot of work to do yet before we'll be ready to open for testing.
