I recently ran across a proto-concept for a one-off RPG that I believe has some potential. Perhaps you could help me develop it a bit?
The concept is thus: Start off the game: Thirty students and one teacher. The setting is a boarding school.
At a specific time (roll a d12 for hour and 3d20 for minute, then flip a coin heads is PM tails is AM) all light produced by the school's lights and the sun itself goes dark. Flashlights, candles, and other things still produce light.
Several students fall asleep immediately (d6), but not the teacher or the players. These students do not wake up.
The main mechanics of the game are then revealed. Every ten minutes of game time, the students lose 1% of 'Wakefulness' They start at a randomly determined amount from 90 to 100. The Teacher, run by the game master, does not lose Wakefulness in this manner. The other students, who have randomly generated Wakefulness (Percentile) do. The Teacher is the DM's PC, and due to his or her adult discipline or some other reason, does not lose Wakefulness unless frightened or under some sort of effect. The Teacher has a flashlight, keys to certain areas, is physically stronger than the players, and somewhat smarter. Not to mention they know the school's layout a good deal better than the players.
THe loss of the Teacher should be a severe and frightening thing, like the loss of the only adult in a crisis situation to a bunch of children SHOULD be.
Every hour, every player rolls a percentile die. If they roll over thier Wakefulness, they fall asleep immediately.
The goal of the game is to find the reason behind the Darkness and the slumber, and to restore things to normal... Before the entire class falls asleep. Players who fall asleep can switch to one of the Students.
Certain effects drain Wakefulness faster. Being Afraid doubles the drain of Wakefulness, but during the effect's run, you cannot sleep, unless you hit 0. Caffeine and tea can restore some wakefulness, and being in a highly buzzed state can restore it over time and prevent sleep further.
Ideas? Interest? Hatred? This isn't really done yet.
