So I was playing StarWars Lego one day, and I worked out this whole system using six sided diie. Regular characters (soldiers, un-important characters) got one die, upper level characters and first stage jedi got two, main non-jedi characters and Jedi Knights got three, and Jedi Masters got four, and ultra powerful Jedi get five. I was thinking about fleshing it out more though, you know, make it a little more in depth.
