Nightmare! The Classic VHS Horror Game
This is what survival horror games looked like in 1991.
Nightmare (aka "Atmosfear" in Europe) was a game for 3 to 6 players. Press play on your vcr, roll the dice to move around the board, and periodically The Gatekeeper will suddenly appear on screen and screech commands at you. Players must not only follow his commands, but must respond to such requests with a loud reply of "Yes, my gatekeeper!"
You draw cards that might prompt you to scream, try to scare other players, worship the tv, or laugh maniacally... all while your increasingly haggard looking Gatekeeper torments and teases you.
it's pretty much one of the most party games ever yinz guys.
If you can't find a copy of the game on ebay, you can try to recreate the experience with the following videos. Just remember to turn out the lights and turn up the speakers...
