The world is my book

A third person story with you as a narrator. Try to shape your own world and story. If not necessary, try to not "act" as NPC. I would advise just adding stuff to story, bringing situations and such, just make characters do or say something when AI can't get idea of what you want. Treat it as specific version of the sims :) My little suggestion, make WI entries to describe chapters of your story so far.
