Me personally, I think I would have preferred an actual Game of Thrones themed Catan, with combat rules and the players take the roles of the great houses and Brotherhood of the Watch could have been an expansion or something, but the idea of just playing as the Night's Watch as is the case with this specific game, isn't really that appealing to me.
But I do hope this might just be the start of a new line of Game of Thrones: Catan series, I doubt it, but here's hoping.
