What is nightmare the board game?

As an AI language model, my training data only goes up to October 2021. As there could be multiple board games titled Nightmare, I will provide general information on board games and the concept of Nightmare.

Board games are tabletop games that involve moving pieces or tokens around a board or surface. The objective is to win the game, which can involve strategy, luck, or a combination of both. Board games are played by two or more players and can have simple or complex rules, depending on the game.

Nightmare is a horror-themed board game that was first released in 1991. The game is designed for up to six players and is played on a special board depicting a sinister castle. The game is managed by a "gatekeeper" who introduces various challenges and dares throughout the game. The gatekeeper is played by a video cassette or DVD, and the challenges often include performing certain actions within a time limit, answering trivia questions, or completing puzzles.

Players move their game pieces around the board, collecting keys and treasures, and trying to avoid being caught by the gatekeeper. The game is won by being the first player to collect all six keys and reach the center of the board.

Overall, Nightmare is a unique and exciting board game that combines horror and interactive elements to create an immersive experience for players.
