Paradox Inversion Core: A Universal Roleplaying System.

What is Paradox Inversion? Paradox Inversion is a tabletop Roleplaying System, designed with an emphasis on ease of use and modularity. Mechanics of each story can be mixed and matched, while maintaining balance throughout. Paradox Inversion is played with 2 or more players (one person to tell the Story, and at least one other to experience, react to it), dice (mostly 12-sided), and paper to record your characters, notes, and other details. The core book clocks in at just around 60 pages, and makes for a quick read.
