Setting

The game is set in the pulp era of the 1920s.^[1][2][3] Player characters are 'Centurions': 'potent individuals of action', born on the first day of the century, and endowed with extraordinary skills and abilities, much like Warren Ellis's conception of Century Babies in the Wildstorm comics universe. It has been released under the OGL with a freely accessible System Reference Document.^[4]

Part of the setting is created in character generation; all characters have ten free-form aspects that have an effect on the game and on the world. Each character gains two aspects from their background, two from what they did in the Great War, and a further two from the stories that would make up an imaginary novel about their life before the game started. They then get a further four aspects by guest starring in two of the other PCs' novels for two aspects apiece.

Rules

Spirit of the Century uses the Fate 3 engine, meaning that all rolls are made by rolling four Fudge dice and adding the character's skill to find the outcome. In addition to the skills, all characters have aspects that can be invoked at the cost of a Fate Point for a bonus or compelled by the GM to gain a Fate Point in exchange for doing something bad for the character (such Fate Points may be refused at the cost of a further Fate Point). Also all characters have a number of stunts that represent things they can do that go above and beyond normal capabilities.
