This narrative game uses a structured series of anthologies, stories, and scenes to create a shared narrative. Players gain narrative ascendancy by using a type of wagering process and an intriguing system using numeric grids created on their character sheets.
The game's actual name is a symbol - the smiling/frowning face masks of classic theater (refer to image gallery). The title Prosopa was used to name the game file itself, and is used here for reference. The game document also uses a variety of other typographic symbols not commonly encountered in game rules.
