All these LCGs that Fantasy Flight Games make must be popular, because they keep pushing out more and more expansions for them. Game of Thrones is no different it seems.
The newest one, pictures here to the left, is the fourth Chapter Pack for the Kingsroad Cycle. This Chapter Pack focuses heavily on the North, with over half of the card geared towards the Nights Watch and Wildlings. You get new copies of certain characters, such as Jon Snow, Janos Slynt, and Coldhands, as well as the LCG’s first version of Ygritte.
A lot more info on the pack here. Enjoy.
