The Waters of Lethe [Free]:
The Waters of Lethe is a roleplaying microgame about people surviving the invasion of the Shadows, memory eating entities. The game uses only up to three six-sided dice, and its rules fit on a single page. During play, characters will be forced to overcome obstacles and gradually lose their memories and personality.
Three traits describe your character: a noun, an adjective and a verb, and you always succeed in your actions... but probably not as you expected. When doing something risky or uncertain, ask the other players what they think could go wrong. The Game Master will then choose a number of those things and stablish them as threats.
You then roll as many dice as traits of your character can reasonably help you do that thing, and assign one of those dice to each threat you're trying to avoid. The numbers assigned determine granularly how well you avoid each threat, being 6 a total avoidance 1 a compelte failure. Any threat without dice will default to a failure.
You can also push yourself to gain an extra die before you roll. But if you do, then you add the value of the lowest assigned die to your oblivion track. When you fill your oblivion track, you permanently lose one of your aspects. When you lose your last trait, your character is removed from the game, unable to fight for her life anymore.
