The PDQ Core Rules is a stripped-down version of the game engine used for Dead Inside and Monkey, Ninja, Pirate, Robot: the Roleplaying Game, and Truth & Justice. It also forms the core system for other games like Ninja Burger, Zorcerer of Zo, and Swashbucklers of the 7 Skies. PDQ has been designed for simplicity, speed, and flexibility in play: three levels of resolution, suitable for any type of situation.
