A term from Scandanavian larp, meaning a game event or improvised theatre play where a fateweb (see this) is interpreted and transformed into improvised acting by the fact that all participants follow their characters fate. Fateplay may be tabletop RPG or larp-event where all are given fates. An improvised theatre play, however, is held before a non-interacting audience.
