I focus very much on the rules and challenges, not so much the emotion.
So, a question, if you don't mind...
How does not having a visual image in your mind prevent you from approaching emotion in play?
I ask because, as a gamer, when I am in emotional play, it is not with an image of events in my head, as if, say, I was doing voice-over work for an animated film. The most emotion I've gotten comes with direct interaction with a person, when no image is really necessary.
