Take control of one of the great houses - Lannister, Stark, Baratheon, Tyrell or Greyjoy - in the struggle for control of the Iron Throne. Each house vies for dominance through diplomacy, resource management, and cunning. Each player controls their army while gathering resources to survive the oncoming winter. A Game of Thrones features a unique phase mechanic and ordering system to keep all players involved at all times.
The second edition of the game features a clarified ruleset (thanks be to the old gods and the new!). It also integrates some of the expansion material that you had to purchase separately to use in the first edition of the game. Also new are the Tides of Battle cards, which bring an element of unpredictability to combat. These cards represent things like weather, morale, tactical opportunities.. anything that might upset the balance of power in a battle. And if GRRM is about anything, it's about killing off the person you thought was going to survive.
