Note 1: This story is told from Sunset Shimmer's perspective.

When does a game become more than that? What if it becomes a game where you are in a race against time? What if you were trapped within the darkness, and you have to struggle to find a way to return to the light? When Pinkie Pie hosts a sleepover where all of her friends, they discover that she has found a board game unlike any they have seen before, and insists the group play it.

This game is interactive... where twists and turns abound... it is a video board game where one must face their greatest fear...

Note 2: This story involves the Mane Seven playing a board game known as Atmosfear, sometimes referred to as Nightmare in other regions. Rather than go into the history of the game, I'll provide two links. One is the article about this game on Wikipedia, and the other is a YouTube of the actual video that is used to play.
