Stories are the heart of the endeavor. Whether start-to-finish as with books and movies, or branching wildly at the player's whim, stories are as malleable as thought.

You might find yourself in a foyer, looking at objects on a shelf, then jump into a snow globe to find a habitat for deer. Each twist, each choice is crafted by the author and her friends.

They might even be watching, play-acting characters in real time, learning from your choices to improve their tale again. From you, they find motivation to continue, to build and learn anew.
