It was good to hear from Jeff again, and especially good to know that he has been exemplifying the concept of "playful play" with his design of Levied Souls, during the two years since we discussed it. You can see those conversations and listen to the audio of playing the game as it stood then at Existential sword and sorcery and Three maybe-maybe-not heroes and that is the point.
We're in the middle of this consulting sequence, and I'm looking forward to trying the rules for cleaving flesh from bone and for spinning one's mind into the abominable vortices. At this point, however, we have focused on the topic of who says what, when they can say it, what they can and cannot say, and whether this is fun. I think it's a good example of how non-abstract the topic of authorities is, and how the details of the things I just mentioned will only be clear in design-and-play terms when the larger issues reach a point of reliable understanding among the group.
I hope you'll check it out and share similarly table-specific, concrete thoughts about the topic.
