Fighting Fantasy is a series of single-player fantasy gamebooks created by Steve Jackson and Ian Livingstone, originally published by Puffin and now by Wizard Books. Although not the first book series to use the gamebook format, Fighting Fantasy popularised the format and spawned dozens of imitators. The popularity of the series led to spin-off board games, video games, role-playing game systems, novels and magazines. In a typical Fighting Fantasy book, the reader will take the role of the story's protagonist, making the character's choices and following their own path through the story. The series distinguished itself from similar series with its use of a dice system which added a role-playing element to the books. Most of the Fighting Fantasy books were set in the fantasy world of Titan, although some are set in science fiction, horror and other fantasy settings.
