A resolution system has the ability to add some flavour to the game so I want to make sure I get this right.
I'm still tossing up (no pun intended) whether to go with a dice system or a card based system.
The card system has the advantage of being catchy and unique and I can tie it to the gambling the raison d'etre of the gentlemen's club, the disadvantage is that I can't think of a really successful system that uses cards for resolution. I'm not saying they don't exist I've just never played one.
The big advantage of a dice system is the familiarity. RPGs and dice go together like email and bacon.
The gentlemen's clubs of the age had several popular dice games which might be useful for resolution. One in particular "hazard" has possibilities but I'm having trouble finding a way to streamline it. Stay posted...
