From Amazon:
Catan the original strategy board game. Your adventurous settlers seek to tame the remote but rich isle of Catan. Start by revealing Catan's many harbours and regions: pastures, fields, mountains, hills, forests and desert. The random mix creates a different board virtually every game. No two games are the same. Embark on a quest to settle the isle of Catan. Guide your settlers to victory by clever trading and cunning development. Use resource combinations- grain, wool, ore, brick and lumber-to buy handy development cards and build roads, settlements and cities. Acquire your resources through trades, cards or lucky dice (even outside your turn). Someone might cut off your road or buy a monopoly. And you never know when the wily robber might steal some of your precious gains. Suitable for 3-4 players.
