Everway was first with implementing, in a commercial game, several new concepts including much more picture-based/visual source material and character creation than usual. Like other works by Jonathan Tweet, the rules are very simple and flexible. It is also one of a few diceless role-playing games. The Fortune Deck works as a randomizer and inspirational tool, and the results obtained by it are highly subjective. In order to clarify their use, Tweet coined some new vocabulary to describe and formalize methods of gamemaster adjudication; these terms have been adopted by the wider tabletop RPG community. Tweet's adjudication terms are: Karma (making a decision based on character abilities, tactics, and the internal logic of a fictional situation), Drama (making a decision based on what moves the story along), and Fortune (letting a randomizer — drawing a card in "Everway", but could also refer to rolling dice in other games — determine the outcome).
