->''Feeding Nazis to Dinosaurs since 2006.''

Award-winning tabletop roleplaying game designed to simulate pulp novels and old serials. Think ''Franchise/IndianaJones'' meets ''Film/TheRocketeer'' in ''JourneyToTheCenterOfTheEarth''. Uses its own dice pool system, Ubiquity, which has been licensed to a couple other games: Desolation, a post-apocalyptic fantasy, and All For One--the Musketeers fight demons.
