Hi Trish,
Yes, it was originally begun as an escape from this reality. I spent much of my childhood alone, and my universe was there as something that seemed more real to me. As yours has, it has received many revisions over the years, though my few attempts at writing stories based on it were unsuccessful, as literature is one of the many things I have always struggled with. Thus, my universe comprises many spreadsheets, maps, detailed star systems and planetary statistics, economics and demographics, and detailed starship specifications. Thus the Wikipedia I am building is far more suitable for what I have created, as would a game based on its creation processes.
It is something that I have to work on every day, at least for a little while.
I wish you luck with your novella. If you ever wish to discuss it some more, feel free to message me. I am always intrigued to learn of other universes.
Sam
