adventures for the T&T system, as well as solos for other tabletop role-playing games. The first commercially successful series of gamebooks was the Choose Your Own Adventure series establishing the "American" gamebook tradition. The "British" tradition, as exemplified by the Fighting Fantasy series, was, by contrast, slightly younger. British gamebooks differ from the American tradition by having rules more strongly influenced by the game mechanics of roleplaying games. The US (late 1970s–) The Adventures of You, a two-book series, authored by Edward Packard and R.A. Montgomery and initially published by Vermont Crossroads Press, laid much of the groundwork for the later surge in popularity of the gamebook format. Sugarcane Island by Edward Packard was written in 1969 but did not see publication until 1976. This became a series when Journey Under the Sea by R. A. Montgomery was published in 1977. Two standalone gamebooks authored by Packard would follow, both published by Lippincott: Deadwood City (1978) and The Third Planet from Altair (1979). While these early efforts apparently achieved some popularity with readers, they (and the gamebook format in general) still did not have a publisher with the marketing strength required to make them available to mass audiences. Packard and Montgomery took the idea of publishing interactive books to Bantam, and thus the Choose Your Own Adventure (CYOA) series was born in 1979, beginning with The Cave of Time. The series became immensely popular worldwide and several titles were translated into more than 25 languages. The series reached the peak of its popularity with children in the 1980s. It was during this period that Bantam released several other interactive series to capitalize on the popularity of the medium (a few examples are: Choose your Own Adventure for Younger Readers, Time Machine and Be An Interplanetary Spy). Many other American publishers released their own series to compete with CYOA. One of the most popular competitors seems to have been TSR, who released several branching-path novels based on their own role-playing games. The most famous TSR series was Endless Quest (1982–). Another strong competitor was Ballantine with their Find Your Fate series, which featured adventures in the Indiana Jones, James Bond and Doctor Who universes. Famous author R. L. Stine wrote several books for this line, including The Badlands of Hark, as well as for other series such as Wizards, Warriors and You. Several Choose your Own Adventure spin-offs and many competing
