Fighting Fantasy
Titan: The Fighting Fantasy World is a book in the "Fighting Fantasy" series of children's role-playing gamebooks, first published by Puffin Books in 1986. Although credited to Steve Jackson and Ian Livingstone, it was actually written by Marc Gascoigne (credited as editor), although mostly based on locations, characters and events already described in other books in the series (including Jackson's and Livingstone's). It is written in the manner of an encyclopedia about the fantasy world of Titan, in which the majority of "Fighting Fantasy" gamebooks are set.
