In the rule book for the Pirates of the Spanish Main RPG, by Pinnacle Entertainment Group there is a reference to future books that explore other time periods with rich ocean-going themes. Alas, my Typhoid Mary streak is still going strong. The Pirates of the Spanish Main RPG line is defunct. This is due to the restructuring of WizKids.
So RP sessions in Plattsburg Bay with gunboats on the lake or whaling off the coast of Nantucket will have to be home-grown affairs.
