Originally part of Kevin Hardwick's Narrative Stance Model, where it was also known as "Director" stance.
It implies playing with an eye towards changing the game or
affecting its development on a metagame level. In Ron Edwards'
adaptation of Stance, these were split into
separate stances. Author Stance includes only controlling
of the character, while Director Stance is
controlling other parts of the game. Author Stance includes
two sub-categories: (1) "Author" Author Stance where the player
then retroactively suggests motivation the character to perform
the acts in question; (2) "Pawn" Author Stance where the player
does not. See Pawn Stance.
