From Google AI:

Agon (Greek: ἀγών) refers to a contest, struggle, or gathering, originating in ancient Greece for festivals with athletic, literary, or dramatic competition, and is also the root of "agony". The term applies to dramatic conflict in plays (protagonist vs. antagonist), specific ballets (like Balanchine's Agon), strategy board games, and modern tabletop role-playing games (RPGs) like Evil Hat's Agon that focus on mythical heroics, as well as gaming hardware.
