What I like about my favorite simulation games is that you can set up a situation and see how it plays out. Sometimes it’s an obvious situation, and sometimes you legitimately don’t know. Sometimes it’s legitimately relevant to contemporary issues, and sometimes it’s a total gonzo fantasy. I did think that writing fiction was different-until I actually wrote multiple books.
In the spectrum of “write completely as you go along” to “meticulous plotting”, I’m somewhere in between. I do make outlines and character lists, as much as so that I don’t forget them as for any other reason. But my final products have frequently either diverged from the outline or incorporated something not in them. Reminiscing on that has made think “a-ha, so it really isn’t that different from a sim.”
It involves me setting up a situation (which is to say the basic plot and main characters). Then it involves me seeing how that situation plays out over the course of me writing and editing it. It is fascinating to look back on my completed books and see how their development unfolded.
