Disney’s Pirates of the Caribbean Online wasn’t as massive as some MMORPGs out there, but it was free to download and free to play.

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.
