When I ran Fading Suns, I decided that I was displeased with the rules. Not only were they another set of combat rules for my players to learn, they have some serious issues for my tastes. They rely on a single die roll for action resolution, yielding a much higher variance than die pool systems, and an ostensibly competent character actually has an unreasonably high chance of failing at tasks that should be simple going by the rules as written.
