This game is absolutely BRILLIANT! I learned about this game from the Dice Exploder podcast, where Jason Morningstar highlighted it as an excellent example of playing with dramatic irony in an episode dedicated to Transparency.
Yesterday, I played the first session, which took us about 30-40 minutes, after which we discussed potential techniques, best practices, and ways to further enhance the dramatic irony for another 40 minutes.
It's a wonderful freeform that allows for exploring this important aspect of story games in a very condensed format! And of course, it generates fantastically interesting scenes.
I've set aside a couple of evenings to play this short game again and again, after which I plan to document the best practices and techniques we developed at the table in a blog post :)
Amazing!
