The Culture: The Player of Games
Space-living elements of seven or eight humanoid species break from their states and corporations, machine sentience arrives at the same time and agrees to help, automation ends scarcity, and Minds vastly beyond humans run the ships and habitats benevolently because they are built to want experience rather than territory; the novel shows the result from inside and shows the Culture toppling the Empire of Azad by steering one game player to beat its Emperor at the game that legitimates it.
