|The Big Model|
We're role-playing! That means sitting around and talking about some imaginary stuff. We have to be describing characters in some kind of universe who are at this moment facing some kind of hassle, and we do things at the table to make things happen to them. A lot of the time, we do this vividly.
Those things do have a nice relationship to one another, for instance. The hassle is usually a nice trainwreck of the facts that these characters are specifically in this spot at this time, and the things that happen are basically the hassle getting worse or coming to an end. And without all the vividness about any and all of this, we wouldn't be having as much fun.
The imagination of fictional events, established through communicating among one another. Exploration includes five Components: Character, Setting, Situation, System, and Color. See also Shared Imagined Space (a near or total synonym).
