Pretty much what the title says! General or specific, important or unimportant, obvious or not so much ... doesn't matter.
The common items included what resolution mechanics are for, situation as a constraint which undergoes change, interactive but non-transitive forms of fun. I think most of the details tied back into these. However, one of them which was only articulated at the end, and also seems to "vibrate" back into everything previously said, is the unqualified desire to play more and to play more games.
I edited the session a little more tightly than usual, as I wanted to focus on testimony, so it loses a little bit of the "teaching glue" such as organizing who talks next when things get exciting, or minor subroutines of confusion needing clarification, or the odd tangent. So this presentation probably comes off as a bit more documentarian, as if a bunch of people independently produced personal statements out of the blue, rather than the messier and slightly-moderated form that I try not to lose in the edits. But in this case it seemed more appropriate to me, to highlight the personal nature of each concept.
The topic strayed a little, which I consider to be valuable for reflection purposes. It's not easy to separate "what I have learned" from "now let me explain what I think," and here, I didn't see the need to separate them unless someone really went wandering. So you'll see a couple of instances of that.
I'd really like to see individual or group recordings included in the comments, and if you do that, please try to stay on topic regarding specific things you've learned.
