By way of ripost Ian Bogost (no relation) says..
When you think about it, it’s curious to pen a manifesto for a ludic century to come in the twenty-first century, when the manifesto itself was such a staple of twentieth-century thought. The term was certainly in use before then, but the modern manifesto as a written prescription that makes manifest certain principles really starts with the political manifestos of Marx, Engels, Bellegarrigue, and others in the mid-19th century. The artistic manifestos of Symbolism, Futurism, Dadaism, Surrealism, and others followed this lead, proclaiming clear, direct, and unyielding principles for creative practice.
So, perhaps there is one fundamental challenge for the Manifesto for a Ludic Century: would a truly ludic century be a century of manifestos? Of declaring simple principles rather than embracing systems? Or, is the Ludic Manifesto meant to be the last manifesto, the manifesto to end manifestos, replacing simple answers with the complexity of “information at play?”
