Agôn

Agôn is an ancient Greek term relating to conflict, struggle, and contest/competition.

The Relation Between Agôn and Games
Historian, David Parlett injected the idea of Agôn into game design with his theory of "formal games and informal games." In his words, “A formal game has a twofold structure based on ends and means” while an informal game has little to no structure. To describe this, Parlett used the idea of a contest as a metaphor, which means “winning” is the “Finish Line” of a game; formal games should have an objective and should be played by multiple people competing against each other.

Examples of Agôn
Most games include Agôn in the form of an objective that can end the game if someone achieves it. Some games contain one winning goal required players to cooperate to achieve, such as “Human: Fall Flat”. There are also games that contain goals player’s must keep secret from each other, such as “ The Werewolves of Millers Hollow” or “[https://boardgamemanuals.fandom.com/wiki/BANG! BANG!]”. More traditional examples of Agôn, include contemporary competitive video games that required two or more players to compete for one single goal.

Role Playing Games (RPGs) on the other hand rarely have a clear goal. Most role-playing games has no “winners” or an ultimate goal to achieve and are more likely compared to "informal games."
