The game's working title was "Project Faith" until it was changed to its current one in mid 2007, suggesting that the game's city is a mirror to its inhabitants. American TV series "Firefly" and its film spin-off "Serenity" were cited as major influences on the setting. Writer Rhianna Pratchett, who was hired a year and a half before the game was released, described the society portrayed in the game as somewhere between an anti-utopia and a nanny state, stating that the game explores the contrast between citizens who give up their personal freedom for a comfortable life and those who prefer to live on the edge freely. O'Brien deliberately chose not to give the city a proper name because it was considered an amalgamation of many different cities, blending both East and West aesthetics. Around two and a half hours of in-game music were composed by electronic music artist Solar Fields. To ensure there was a good flow between the player and the game world, the score was designed to be very interactive and different parts transition seamlessly. The game's main theme song was composed by Swedish producers Rami Yacoub and Arnthor Birgisson and performed by Swedish pop star Lisa Miskovsky. The game went gold on November 6, 2008 and took nearly two years to complete.
