I do this to help my sons. I write medieval fantasy as a hobby (been a D&D DM for years), but I'm also a coder and merged the two (like a MUD or Text based RPG): collaborating medieval fantasy character building while writing asynchronously with other writers, is it possible?

Yes, you can do all: Ruler of Kings II Text RPG Solo Play by Post Looking for writers to come on board and help build the world!
