Day 16 - Dream.
This is a tough one.
I can say with certainty that some of the game adventures and sessions I've run have been inspired by some of the dreams (and nightmares) that I've had over the years, though nothing specific comes to mind right now.
That said, these days I've been dreaming of a roleplaying game based on the Shattered Sands series of books by Bradley P. Beaulieu. I think that would be so cool; it's the kind of epic type of fantasy that I'd want to run, but would also depend on the game system it uses.
And there you have this sixteenth post for #RPGaDay for August, 2019. Comments, thoughts, questions, etc. are all welcome, of course.
