Mercator

A historical role-playing game that adapts the Classic Traveller rules to the Roman Empire of the 1st and 2nd centuries AD. Players take the roles of traders, sailors, veterans, and other adventurers traveling across the Mediterranean, negotiating deals and transporting goods such as dried fruit and fish sauce. The campaign focuses on travel, trade, and adventure, with opportunities for smuggling, theft, ambushes, raids, piracy, and other schemes. It presents an adventure-oriented version of imperial Rome rather than a strictly accurate historical simulation or a magical fantasy setting.
