From the announcement:
The Brothers of the Night’s Watch seek a new leader from among their ranks. Jeor Mormont wishes to promote one who can improve the infrastructure of the Gift, the bountiful and undeveloped area south of the Wall bestowed to the Watch by the Starks thousands of years ago. Drawing sustenance from the unforgiving landscape of the north offers enough challenges, but whomever takes up this task must also man and defend the Wall against the onslaught of Wildlings fighting their way into Westeros. Many brothers now compete to build, defend, and do what they can to protect Westeros, but only one shall rise above their brothers to become the new Lord Commander. But be wary—the north holds many dangers, and winter is coming.
Fantasy Flight Games is excited to announce A Game of Thrones Catan: Brotherhood of the Watch, a standalone game of resource gathering and trading based on the classic Settlers of Catan. The battle to defend the Realms of Man begins in this new strategic game grounded in the engrossing world of George R. R. Martin’s A Song of Ice and Fire series and adapted for Catan by Klaus and Bejamin Teuber.
The game will be on display at Gen Con, where you can get a demo, and will be on store shelves in Q4 of this year.
