I'm really interested in exploring how the notion of performance informs and shapes gameplay in the tabletop space. There's the extremely literal idea of play as performance in the form of Actual Play podcasts/VODs/streams, but I think there are some really interesting questions to be explored, in play-by-post games in online spaces (where performativity is already such a pervasive facet of the medium) or in playing singleplayer games for an audience of one.
For people who have participated in or run Actual Play games—how do the principles of play change when you're running a game solely for yourself, versus for a closed group of friends, versus for an external audience? To what degree do elements of "traditional" performance (directing/acting/improv/etc) make their way into your games? For people who are running those games, or for those who just watch/follow them—how does your notion of play change or morph when your audience is following the game live, versus engaging with it after-the-fact?
