The game is a fascinating reading and perfectly captures the feeling of Borges' style of writing; many times I've smiled while reading the text. Also, I really appreciated that the author tried to tie those references to rules and not just suggestions (like "passing the turn with a dismissive gesture").
I'm not sure I understood correctly the rule about bifurcation, namely "The chapter may preserve the unity of space or time, but not both".
I think that - similarly to my own game - "La ciudad" can actually be played consistently in a single session (I must admit I didn't take the restriction of "play this game in multiple session" as a fundamental one; on the other side it was not strictly part of the theme, rules or ingredients...).
Very curios about playing it.
