Game of Thrones' official PC and console counterpart has been in the works for seven years, say the developers at French team Cyanide Studios.
"When we started working on the game, the TV series was only a rumor," explains lead designer Sylvain Sechi in the adaptation's latest trailer. "So we created our own environments and our own characters but always with total respect for the universe of [author] George Martin."
"He gave us precious information about everything we have created, including the designs of the places, all the artwork we produced," continues project director Thomas Veauclin.
"The story is told from the point of view of many different characters," Sechi says, referring to The Song of Ice and Fire novels, upon which both the TV series and video game are based. "We decided from the very beginning that we wanted to go the same way, so we built the script from the point of view of two different heroes."
Game of Thrones: The Game is released in North America on May 15, at the same time as video game juggernauts Diablo III and Max Payne 3, but has serious brand name recognition already in place.
The European equivalent goes on sale during the quieter week of June 1, where driving game Dirt: Showdown and Lego Batman 2 are its main shop window rivals.
