In a few words :
Cyanide's CEO is a great fan of ASOIAF and asked GRRM many years for the license.
GRRM has played a little, but didn't seemed to be a gamer.
Ty played more and read all the scenario.
The game is focused on A Game Of Thrones. Royal bastards are an important part of the story.
The game does not follow the characters of AGOT, but runs in parallel to the story.
The "pause active slow motion" fighting system is a bit like Kotor.
Some french fans have been able to test the game, liked it and gave them some advices.
Playtests with players who didn't know ASOIAF has been done too.
The game has been developed before HBO's Game Of Thrones. It will look different (King's Landing for exemple)
The game is due to the beginning of 2012.
All the dialogues will be voiced.
