MANIFESTO! is a game for individuals or groups of 2-6 players. In each round, players are dealt one random card from each category: Provocation, Orientation^†, Opening, and Tone. Substitutions are allowed. The different categories define a unique parameter or constraint. Provocation suggests a broad topic or theme (e.g., ‘Better for whom?’, ‘Challenge inequality’); Orientation designates the type of manifesto players will create (e.g., ‘Diagram’, ‘Declaration’); Opening offers the initial phrase (e.g., ‘We declare’, ‘Imagine’); and Tone is the rhetorical register to be used in addressing the subject or audience (e.g., ‘Urgent’, ‘Hopeful’). Players use these constraints as prompts to individually or collectively write, sing, enact, draw, or build their manifesto. Each round can be timed (e.g., 10 minutes) or open-ended. When a round is complete, players may vote for the ‘winner’ (e.g., the most persuasive manifesto).
