@ajbz What are your research goals? There are lots of types of #GMless #ttrpg. Some are oracle based, like Ironsworn. You can also use a #GMEmulator like Mythic to play the rpg of your choice without needing a GM. Another type is card-based prompts, such as For the Queen and its descendants. Plus there are journaling games like Thousand Year Vampire. So many different types!

@auguryignored I think using a #GMEmulator with another #ttrpg could count as such a mashup, as you have to decide which part of play you'll handle with the original system vs the emulator. We've used #MythicGMEmulator with #Genesys.
