In Catan: Seafarers you control a group of bold seafaring settlers exploring and taming the wild, uncharted Isles of Catan. Each game brings you to new seas and new lands. You might even discover the precious gold fields (a very valuable new terrain). Every game is unique and full of fun! The Seafarers Exansion Package includes the Base Settlers of Catan Game as well as the Seafarers Expansion. Both are needed in order to play the Seafarers Expansion.
