"One of the very exciting things about
(maybe I'll just cave and call them 'Story Games', which I am not sure I like) is that when they're done right, they allow us players to tale those things that our subconscious has popped up as 'creativity', and to address them in the context of the game and story. The setting is usually sufficiently abstracted from our reality that it is safe for us to explore modes of behaviour that we would not otherwise use, but as Bettelheim suggests fairy stories do for children, the scenes and events still resonate for us in a meaningful way. When we've explored them enough, we can put that character away (or we'll find that the character is now 'boring'). This is healthy."
I'm Done with This Guy! is, in many ways, the mirror image of the Eight-page Character Background.
I see recognizing that you are done with a character as healthy, functional play, whereas the 'eight-page character background guy' attempts to bring his character into play at the moment that 'I'm done with this guy! guy' is hanging him up.
