Anyone like the sound of this?
Massively Multiplayer version of Sid Meier's Pirates!, with the world, rather than the Carribean as a stage. Ships from all areas of the globe to capture and pillage (Chinese Junks, Arabian Dhows, Malay Proas), more nations to sign on with, etc. The coast of Ireland get too hot for you? Journey round the Cape of Good Hope and enter the Indian Ocean to search for fat Indiamen.
Toss in customizable characters, some RP-support like the ability to play for the 'establishment' and join the navy, adventurous options like searching for unique treasures or other such...etc.
