Settling individual states with preset, real-world cities and regions is a good way to extend the world of Catan for novice and experienced players. In addition, you can learn interesting facts about the cities of the respective state.
This series started in 2007 with “Die Siedler von Hessen” (“Catan - Settlers of Hesse,” the English-language version of the game, was published in 2009); various game maps of other German federal states and popular regions such as Mallorca have been published since.
Starting in 2009 with “Catan - Indiana & Ohio,” our friends at Mayfair Games annually publish a US-specific regional edition as well.
Please note: You need a "Catan" base game to play these regional editions.
