New South Wales
Another unofficial expansion/ scenario I have made.
Requires Seafarers and 12 Barbarians (preferably those from T&B but any 12 counters will do).
In this scenario you attempt to drive barbarians of the islands near Catan in order to settle these islands, but the barbarians are fighting back, preventing ships, and later on even roads from being built.
Rules, diagrams and tips are found at: http://www.boardgamegeek.com/filepage/43848
Also of mention, I have created a special Amalgam hex that can produce specific resources depending upon which corner of the hex a city/ settlement is on.
