Anno 1503 Treasure Monsters Pirates

Anno 1503 Treasure Monsters Pirates brings the excitement and the scares of the 1800s into the 3D cityscapes of the Caribbean. The game contains 10 pirate islands spanning the breadth of Spain and England, in which time only translates as a magical time of the year.

Here's the official blurb:

Anno 1503 will feature an enhanced version of the popular Anno 1503 game engine. New features in the PC version include the introduction of the trading game features: towns, casinos, castles, and trading houses.

Anno 1503 Treasure Monsters Pirates will be released in March.
