  ==Second edition==
  In October 2011, the revised second edition was released by Fantasy Flight Games, with some minor changes to gameplay as well as new updated board and House card graphics. The second edition includes the additions introduced in the ''A Clash of Kings'' expansion to the base game (House Martell, siege engines, and ports, which are printed on the board). The presence of House Martell has resulted in the redesigning of the southern part of the map to have more regions. Other changes to game play include alterations to the starting positions of units for some Houses (such as Greyjoy), the abilities of house cards, the effects of consolidate power and raid special orders, and the possibility to use Tides of Battle cards to affect battles.
