In Shadow Lords all conflicts are resolved in the same way: you create scene traits (things that influence the narration and give you fictional positioning and can be physical things or abstract ideas or whatever) and inflict consequences (things that influence the characters negatively, from wounds to “ASHAMED OF MY DETERIORATING HEALTH”). Usually conflicts are pretty fast in my game but you can focus on such a duel of wits if you tell the players the point is not to defeat the queen but to convince her trough fictional positioning and mental or social consequences. As gm you can also spend your Shadow pool to complicate things if they do something not appropriate such as physically threatening the queen.
Thus you can model easily that kind of social conflicts without going too mechanical.
On the other hand through drives (character beliefs and goals) and dark talents you can easily model a strict cigs of values.

The basic game is geared toward epic mythological action, but is very easy to back to model anything. It’s a complete rpg but also a toolbox 🙂

this year I will release the free core of the system in a sample one shot adventure. Keep tuned for info on me or http://www.shadowlords.net , there is also a Facebook and Google+ pages
