[A] Actor Stance
The Actor Stance is the one in which the player contemplates
what she can do to portray her character more effectively to the
other participants in the game. That is, you use it when you
have already fixed what your character is going to do -- and
your concern is primarily portraying her to others.
This is different from Author stance because it is not
concerned with character development -- instead of writing the
character or trying to think as the character, the player
consciously trying to portray the character as defined. (i.e.
"Michael has a weakness for women, so I'll say pick-up lines
to this NPC.")
Audience Stance
The position from which the player observes, enjoys, and
evaluates the game or aspects of it as himself, rather than as his
character. This is also a meta-game stance, as it refers to the
player's viewing and interpretation of the game, which may be
very different from the character's. This stance is the stance
from which things like dramatic irony or historical accuracy are
judged. It is also the stance adopted whenever the player
witnesses an in-game event of which his character is utterly
unaware.
[C] Author Stance
The position from which the player evaluates the game with an
eye towards changing it or affecting its development -- either
through her character or possibly through the world itself. The
player adopts this when consciously writing new parts of her
character's background, for example. Usually it is associated
with the player watching the development of the game, and trying
to spice it up by throwing in new twists (i.e. "Hey, we've just
gotten involved with pirates -- why don't I write in that my
character's ex-girlfriend was killed in a pirate attack!")
Thus, the player is trying to stay consistent with the
character as defined, but isn't thinking as the character.
[D] In-Character Stance (IC) or Immersion Stance
The view of the game from within the inside of the game world
and its reality, usually from within the mind of a player
character living within that reality. The player is thinking
as the character -- he doesn't acknowledge Out-of-Character
(OOC) information and tries to concentrate on what the character
is experiencing. In theory, acting In-Character becomes second
nature -- the player does not look at his character sheet and see
"Weakness for Women". Rather, he hears the GM describe a woman
and reacts by saying a pass at her.
There are a lot of conflicting claims regarding this stance.
Everyone agrees that it is difficult to get into. Once there,
some people talk about having different emotional responses or
different personality types (see below). In general, this is
said to take much preparation effort to drop into -- making the
character feel real in your mind. It also is fragile:
distractions can drop you out, making you uncertain of what the
character would "really" do.
[?] `Deep In-Character Stance'' (
`Deep IC'')
This is a possible deeper version of IC stance, where the
player begins to "channel" her character and just be that
person. In theory, this is likened to certain mask work or
experiences of spiritual possession -- that is, even though the
character is not an external entity, the player feels as though
something else were taking over, and she is unable to control
what the character is doing in the game.
