Greets. I'm an old school DM. I do this to help my sons on the Autism Spectrum: I write code for medieval fantasy as a hobby (been a D&D DM for years), but I'm also a writer and merged the two (like a MUD or Text based RPG collaborating medieval fantasy interactive character building while writing asynchronously with other writers, is it possible? Can you alter a medieval fantasy story made for everyone? Do it on your laptop or mobile anytime without having to install an app for free? Yes, you can do all: https://www.RulerOfKings.com
Understanding special needs I believe the game is accessible for the blind, deaf as well as those who have social anxiety.
There are lots of videos there that explain everything. Looking for writers to come on board and help build the world!
Note: Please understand that the game runs within a cultured community thus catering for a more mature user that is interesting in writing and not merely passing through.
