To anyone interested in the possibility of realistic RPG combat, be sure to check out our card game in the making, Audatia. It is the first realistic, playable system of violent conflict resolution I've come across. There are surely other tabletop RPG uses for it beyond the duelling game itself.
The core of the game is a fun, tactical, rewarding duelling card game about two guys with swords facing each other. It is very closely based on the Fiore school of medieval swordsmanship, making few compromises from the art - everything that works in the card game works in real life and vice versa.
It doubles as a teaching tool for the theory and tactics of the medieval (Italian) longsword and associated terminology.
