I even participated myself, writing a short screed called "KILL UNITY; WE ARE ENGINES." It was fun to try to figure out a specific aspect of games that I cared about, and to try to distill that into entertaining hyperbole. Remember: no nuance, no relativity, just pure belief! Go ahead and let your flag fly, and perch it on the swollen corpse of the old world order!
Here's the inspiring blurb, copy and pasted from the itch.io page:
THIS JAM IS FOR COLLECTIVELY UNCORKING OUR UTOPIAN ENERGY IN 2018
In times of crisis, uncertainty, conservatism and even just standard personal disappointment people overwhelmingly retreat to saying “be practical!” This doesn’t necessarily imply a way that is meaningfully better than any other but instead coerces you to chirpily go along with the way others are already comfortable doing it, or comfortable with you doing it, and keep and alternatives or resentments on priv.
Manifestos are important precisely because they are impractical. Whether positive or negative, whether embracing potential worlds or outright rejecting the one you’re in. They are visionary, they demand, they refuse. Manifestoes can be of any scale, defining your personal aesthetic or how to fix the entire world, but they cannot be satisfied.
