Nightmare: The Video Board-game(1991)

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.
