The game requires 3–6 players to attempt to collect keys while trying to beat the clock included on the video cassette. At random intervals, the game stops and The Gatekeeper appears to either taunt, reward, or penalize the players in a variety of ways. Prior to beginning the game, the players are required to write their "greatest fear" on individual slips of paper. The game is won by collecting six special keys before making it to the center of the game board where the player draws a 'fear'. If that player draws someone else's fear, the tape is stopped and that player is declared the winner. If no one is able to accomplish this within 60 minutes, The Gatekeeper is declared the winner.
Characters
The six Harbingers in the game are: Gevaudan the werewolf; Hellin the poltergeist; Khufu the mummy; Baron Samedi the zombie; Anne de Chantraine the witch; and Elizabeth Bathory, the vampire. Each of the Harbingers is based on either a real person or a myth, except for Hellin. Hellin, "in hell" reversed, is the only Harbinger entirely created by Brett Clements. Hellin is also the only character with limited background information, as Brett wanted players to use their own imagination for this character. Baron Samedi got his name from the voodoo loa of the dead, though the game's creators misattribute him as the ancient Arawak Indian God of the Dead. Anne de Chantraine is based on a 21 year old French lady who was burned at the stake for witchcraft. Elizabeth Bathory is based on a serial killer who is believed to have murdered and drunk the blood of about six hundred and fifty virgin girls. Khufu is based on a Fourth DynastyEgyptian Pharaoh. Gevaudan is based around a man who was hunted by armies of people for supposedly carrying the sickness of lycanthropy. The final character in the game is the Gatekeeper, whose job is to make sure the other characters cannot escape from The Other Side to the real world. The Gatekeeper's character is based on the old cemetery gatekeepers, whose job was to guard cemeteries from grave robbers.
Video
Packaged with the game is a sixty-minute video cassette that explains how to set up and play the game. The video contains footage of The Gatekeeper, a man who often interrupts the game to occasionally punish or reward the players at random. For example, if a player fails to answer him with "Yes, my Gatekeeper", he may banish them to the Black Hole. At the end of the game, if no player has won, the Gatekeeper appears and ends the game, declaring himself the winner.
Development
and Brett Clements met in 1982 – they were reporters for Simon Townsend's Wonder World – and a year later, they both set up their own television production company, A Couple 'A Cowboys. They developed a pilot and took it to Village Roadshow, who within 24 hours signed a marketing and distribution agreement. Nightmare was released in September 1991. In Europe, the game was renamed to Atmosfear to avoid legal issues with the name Nightmare, which was already taken. On the game's release, a marketing campaign was launched with advertising appearing on television and in cinemas.
Reception
The game was popular in Australia, leading to sold out "dance parties" and a number of advertising deals, including one with Pepsi. A song and a music video were also created for the game. Clements and Tanner sold the two millionth board game during the 1993 Christmas period.
Expansions
Following the success of Nightmare, four game expansions were announced but only three were released. Each expansion comes with a new tape and new time and fate cards, with a different character hosting each new tape. Nightmare II is hosted by Baron Samedi released in 1992. Nightmare III is hosted by Anne de Chantraine released in 1993. Nightmare IV is hosted by Elizabeth Bathory released in 1994. The game's fourth expansion, based around Khufu, was going to be released in 1995, but faced with declining sales of the series, it was cancelled and replaced by The Harbingers. During an interview with Hard Copy in 1992, they discussed the possibility of there being a movie based on the characters. This, too, fell through because of the declining sales.
