Sleep Is Death (Geisterfahrer) by Jason Rohrer is a turn-based 2-player storytelling game in which one person plays a character and the other controls the game world. This creates a story-driven role playing experience in which traditional AI and game mechanics are replaced by an actual, human director. The contents of the story are completely up to the player.
While the controller can prepare a script, graphics assets and even music in advance using a simple editor, the unpredictability of the interactions between player and controller creates a unique outcome for every game. Players have to react spontaneously, since each side only has 30 seconds to perform the next move. At the end of each game, a screenshot flip-book of the story is created and can be shared with others.
The game can be played over LAN or the internet. A single purchase consists of two copies of the game, for both platforms.
