While I have started and sometimes even half-finished a baffling amount of (science fiction and fantasy) writing projects in the past few years, every serious project I begin seems to smash into a concrete wall right after it has gotten up to speed. Other issues aside, I have come to realize that one of the reasons for that are my overdeveloped settings. Originating mostly from many years of tabletop RP gaming (and sometimes just from a lot of time spent on them before starting a never-finished project), these worlds are places I am intimately familiar with and that I have developed to a level of granularity that makes them unwieldy to use in a story. I find myself trying to fit the plot around the setting that has been established, rather than making setting and plot form a consistent whole. This causes a dilemma for me: If I create a new setting for a story, I feel like I have wasted years of hard work building these words, even though they were built entirely for a different medium. A large part of my goal as a novice writer is to tell the stories of these worlds. If however I set a story in one of these worlds, I am limited by their complexity and and even more by my familiarity with them. I have told so many stories in these settings that I find it extremely hard to establish them properly so that an unfamiliar party can understand and enjoy them. Contributing to this is of course a certain inability to tell what details of a setting a reader would really need to understand it. Being as inexperienced as I am, this issue has led my in circles for a while now, stunting any progress I could have achieved. Has anyone here experienced something similar or can imagine the situation? I would really appreciate any advice you can offer.
