I assume you are familiar with "
stance theory"? Character agency would be expressed in things like actor stance. Player agency would be expressed in director stance. Pawn can go either way (since it isn't really much about the character
qua character), and author I would say
leans toward player agency but in narrow circumstances would express as character agency instead.
Do you consider these stances to be equally irrelevant, then, with pawn and actor merely being subsets of author and/or director stance?
