This refers to modifications created for the popular PC game Mount & Blade: Warband that incorporate the world, characters, and lore from George R.R. Martin’s A Song of Ice and Fire book series (adapted into the Game of Thrones television show). These modifications typically overhaul the game’s original setting and mechanics to provide an experience more closely aligned with the fictional Westeros.
The significance of these modifications lies in their ability to provide fans of both Mount & Blade: Warband and A Song of Ice and Fire with an interactive experience within a beloved universe. They expand the game’s lifespan, offering new challenges, storylines, and strategic opportunities. The popularity demonstrates a strong desire for player agency within established fictional worlds.
