Disney’s Pirates of the Caribbean Online isn’t as massive as some MMORPGs out there, but it’s free to download and free to play. (There is premium content available only to paid subscribers, however.) You can create your own pirate character, acquire and crew a ship and set sail for adventure — and treasure!
Another geeky way to get into the nautical mood is to learn the lyrics to “Major-General’s Song” from Gilbert and Sullivan’s comic opera Pirates of Penzance:
I am the very model of a modern Major-General,
I’ve information vegetable, animal, and mineral,
I know the kings of England, and I quote the fights historical
From Marathon to Waterloo, in order categorical;
I’m very well acquainted, too, with matters mathematical,
I understand equations, both the simple and quadratical,
About binomial theorem I’m teeming with a lot o’ news,
With many cheerful facts about the square of the hypotenuse. Etc., etc.
