Cynaide began development of the Game of Thrones RPG well before the HBO series blew up, but had no trouble adapting material from the TV show to its game.
Speaking to Xbox360Achievements, lead designer Sylvain Sechi said it was "quite easy" to work assets from the show into the game at such a late stage because both interpretations were worked to follow the original books closely.
"Since we're very faithful to the books and the show is very faithful, every media blends into that one universe," he explained.
"It's not like the books have a very different vision of the universe to the game or the TV show. We don't have three different visions of something. We're all very close in terms of respect towards the universe of A Song of Ice and Fire, so it was more a question of what stuff we should take from the TV show to put into the game and what are the things we shouldn't do."
Sechi gave the example of the throne room in King's Landing, which he says doesn't necessarily look the same, but looks familiar because it shares elements drawn from Martin's descriptions - although the iconic Iron Throne is shared.
There were some areas where Cyanide chose to draw on the TV series, having tried to figure out what key visual elements fans would want to see.
"Top of the list was the characters, because Game of Thrones is more about characters than places," Sechi noted.
"The characters are the heroes, their House is part of that hero and the likenesses of the characters and the sigils are important. We got the actors and their voices, as we felt that was important."
Cyanide also went out of its way to preserve familiar music. Read the full interview through the link above.
