That's a good point about a shared victory and the possibility for a "neutral lack of success." I was referring to a win/lose in terms of someone wins and someone else loses, but you bring up something super valuable with this idea of risk within a liminal space. Plus, I absolutely agree that mistakes often offer more insight than success, especially (in my opinion) when it comes to collaborative improv. I will mention that a lot of Neo-Futurist plays have scripts, but many involve both a script and room for improv, and some are wholly improvised. Regardless of whether the text of the play is set beforehand, performance is itself a daring act enabled by that liminal space you're discussing. I think some researchers refer to it as "the magic circle?" Anyway, I think you've thought just deeply enough about this, because selfishly, I appreciate your thoughts :)
