Dream Park

Blurb

Dream Park is a 1981 novel written by Larry Niven and Steven Barnes set in a futuristic amusement park of the same name. It was later expanded into a series of books.
The books describe a futuristic form of live action role-playing games, although the term was not in use when the original novel was published. The novels inspired many LARP groups, notably the International Fantasy Games Society, named after a fictional entity in the book. A company by the name of Dream Park was founded in the mid-1990s to try to realize as much of Dream Park as possible, but eventually went out of business.
The Dream Park novels were written by Larry Niven and Steven Barnes. The novels set in Dream Park are:
Dream Park - Locus Award nominee, 1982
The Barsoom Project
The California Voodoo Game
The Moon Maze Game
The Dream Park series is set in a near-future Earth, the first book taking place in March 2051. Technology is used to create realistic games in which participants act out the roles of free-willed protagonists in various stories. These are role-playing games and foreshadowed many aspects of modern live action role-playing games.
The sets for the games are quite elaborate.
