I didn't find the rulebook PDF in the support section.

When will it be available?

yeah where is the pdf? The game is already out but no pdf so far. Please post it!

I find this annoying and detrimental to sales.

Many players of the living card game may wish to see what the rules changes are to gauge this game's suitability as a purchase for a spouse or light-gamer friend.

The rules are the same as the LCG, they just changed the cards and dropped most of the keywords (only limited, stealth, and renown are in the game). The decks are quite well balanced against each other, making it a great 2-player intro game; much better an intro game for 2 players than the core set.

Not sure when it was put up, but the rulebook is available here: http://www.fantasyflightgames.com/ffg_content/game-of-thrones-HBO/Game-of-Thrones-rulebook.pdf
