Has anyone run Shackled City with the use of gunpowder weapons? I'm running a Renaissance/Swashbuckler campaign along the lines of the Three Musketeers (lightly armored characters, gunpowder weapons and rapiers as the weapons of the day). I was curious if anyone else has done something along these lines and what, if any, modifications were made to the various villains in order that they fit in better with the type of setting.
