If the world you’re building doesn’t make you hunger, doesn’t flood your mind with fascinating ideas and tragic possibilities, you might be doing it wrong. This is supposed to be fun! Don’t hold back. Don’t compromise your vision, even if it seems to go against the norm.
Intent is everything and yet intent, especially in a good novel, can be hidden. Life itself is filled with perspectives, interpretations, assumptions, rumor, accusations and skewed agendas.
I’m building things in manageable parts and keeping all of it contained within a specific process as I write. So there’s really only one way I know how to answer this question for you and that is the way I experience it.
Now the most important thing you’ve got to keep in mind as a writer/game creator is—YOU are the one in control here. I know that’s a given, but some people (myself included) have to fight a habit at times, of going to others for some validation.
