Rise through the the ranks of nobles the old fashioned way, by backhanding your way to the top and duelling the men to the top. Be careful, many are going to be far out of your league at first, you can attempt to cross paths after lavish balls are held, maybe take the place of a low rank noble, but high enough to earn a spot inside. With new titles comes access to better duelling swords or guns, only one or the other so choose your battles wisely, especially since the challenged gets to pick the weapon. Show your different levels of contempt by challenging a noble with different accoutrements; with a bare hand, the usual, honourable way. A piece of held food, to show contempt. Maybe even a gauntlet, who knows you may end the fight before it begins, although that may come back to haunt you later when they themselves seek a duel.
Gameplay would be in two parts, the party/ball where you meet people, impress women and challenge men. much lighter and more humorous. The duels are first person, but from the perspective of the other person in the duel, you have to line up the pistol in slow motion from their point of view, you will know the gun is lined up when you can see the glint off the end of the barrel. The sword fights are also from their perspective, giving you an edge that you can try foresee what they do and learn how they telegraph attacks
