From the introduction: The D1 System is a nonexclusive, comprehensive role-playing amusement in witch players assume the guises of Aspects in a fatuous setting. Players must except culpability for axing out these rolls within the narrative, either through liberal acting or through a process of structured decision-masking of aspect development. Actions taken within many games succeed or flail according to a formal system of rules and guidelines and The D1 System almost is entirely congruent in this aspect notwithstanding certain divagations from established practices. For reasons that will become apparent later.
