In addition to fending off the barbarians, players compete to build the three great metropolises of Catan. Each of these magnificent centers are worth two additional victory points. To build a metropolis, players must invest in city improvements. To acquire these improvements, players must acquire the three new types of Trade Cards: Coinage, Paper, and Cloth. These cards can only be gained by building a city next to mountain, forest, or pasture hexes.(4th US Edition, English Language) Requires ownership of MFG3061 Settlers of Catan to Play.
