re-reading Excession right now! this is some wonderful backstory in this article:<p>> <i>Banks has noted that he spent much time playing the Civilization computer game (appearing to refer to the first version of the game series) before writing the book and that it was one of the inspirations for the concept of the 'Outside Context Problem' central to the novel. In an interview, Banks specifically compares this to having a Civilization battleship arrive while the player is still using wooden sailing ships.</i>
