I'm trying out Mythic Game Master Emulator with Dungeon World. I've only done a few sessions of game setup but I'm already very impressed with the GME. I'd love to hear from you if you have thoughts or questions about solo roleplaying in general, Mythic in particular, or even just tabletop roleplaying in general.
