  ==Sets and expansions==
  When it was released, A Game of Thrones was introduced as a CCG. The cards for the AGoT CCG were organized into numerous sets and expansions that could be mixed together and used interchangeably. A ''block'' consisted of a ''base set'', up to two ''expansion sets'', a ''premium starter'', and often one or more promotional cards.
  Typically, a base set consisted of 240 cards available in either starter decks, consisting of a mix of fixed cards and a random assortment of other cards, or booster packs, consisting of 11 randomly sorted cards, of which 1 is rare, 3 are uncommon, and 7 are common. Booster packs were generally shipped in groups of 36, creating booster boxes. Expansion sets typically contained 150 cards, and were only distributed as booster packs similar to those of a base set. Premium Starters consisted of two or three pre-built decks of fixed cards, typically reprints from earlier sets, but also introducing 10 new cards as well.
  Within a base set and expansion set, the cards were divided into groups based on their frequency of appearance, with rare cards being included the least frequent, uncommon cards slightly more frequent, and common cards being the most frequent. Also available in regular and premium starters were a specific number of fixed cards that always appeared in that packaging. Also available were ''draft packs'' which consisted of 1 ''draft'' card, 5 ''plot'' cards, 6 ''house'' cards and 8 ''locations'' that are generally useful to any deck, and allow for a more level competitive field during ''draft'' tournaments.
  In late 2007, the A Game of Thrones CCG was converted to the A Game of Thrones LCG (Living Card Game), which ended the random booster packs in favor of fixed packs, called Chapter Packs, released on a roughly monthly basis. Chapter packs consist of 60 fixed cards - 3 copies of 20 cards. The Core Set consists of 4 preconstructed decks consisting of Stark, Lannister, Baratheon, and Targaryen, and is marketed as a starting point for a new player. It will also include a game board, power tokens, gold tokens, as well as game pieces to use for the multiplayer titles.  Along with the switch to the LCG, there has also been more of a focus on the multiplayer aspect of the game, now referred to as Melee, rather than the head to head play, now referred to as Joust.
