Settlers of Catan (a.k.a. Die Siedler von Catan) is a board game by Klaus Teuber. The goal of the game is to reach a certain number of victory points before the other players, via building roads, settlements and cities and by having other accomplishments, such as having the longest road or the largest army. Because of its very unusual non-zero sum game mechanic, many economics professors use this game to teach concepts of comparative advantage and other economics concepts.
