Cthulhu Obscura

A lightweight roleplaying game for Lovecraftian and mythos-themed adventures, including solo scenarios. It uses five differently coloured six-sided dice, a pencil, and an eraser, with rules contained in four A4 pages. Players create characters whose personality traits influence investigations and the outcome of challenges. The simple, adaptable system can be used with existing adventures written for other rulesets, and may be modified and shared freely.
