I've been involved in creating Audatia - a card game based on the Flower of Battle by Fiore dei Liberi. The game's original purpose was to serve as a teaching tool to learn the theory and terminology of the medieval combat system they're teaching at the School of European Swordsmanship.
In development it turned out that it's actually going to be a kick-ass dueling game, too. We've made very few compromises. When you play a duel in Audatia, it's going to make sense when acted out with real swords.
As a teaching tool, it really shines. The terminology and logic of the moves on paper never made sense to me when I was studying the art a decade ago, but it's all clicking now... and I'm itching to get back at it!
