Playing Kingdom Death and Ironsworn over the past 4 years has been an enlightening experience in gm-less style play. In short, the fondness I have is purely driven by the enabling nature it provides.
Regarding play with my partner I aim to provide an experience that reinforces teachings through practice. She wants to feel more comfortable flexing narrative muscles with the nephews. I want her to be able to accomplish that when I am not there. If I just run a standard GM / Player structure she will not develop her skills of stitching together loose ideas into a cohesive whole as well.
My selfish goal is to make more GMs in my life.
