Black Vulmea, over at Really Bad Eggs, smartly encouraged the use of a campaign-specific Appendix N to inform the players about the intended tone of a campaign. Therefore, I present my Appendix N for my "Pirates of the Spanish Main" campaign:
"Brotherhood of the Wolf"
"Le Chevalier D'Eon" (available on Netflix!)
"Pirates of the Caribbean" film series (especially "Curse of the Black Pearl" and "On Stranger Tides")
Black Vulmea's Vengeance by Robert E. Howard (1976 Berkley paperback containing REH's pirate tales)
Captain Blood: His Odyssey by Raphael Sabatini
On Stranger Tides by Tim Powers
Pirate Latitudes by Michael Crichton
The Savage Tales of Solomon Kane by Robert E. Howard
Lots of monsters, not a little magic, tons of swordplay, and plenty of piracy.
