Cult of the Wind is a game about people who pretend to be airplanes.
"In an unknown time and place, a cult that worships the wreckage of ancient airplanes gathers to mimic the dogfights of old. With the peak of humanity far behind, their world is a mausoleum to a lush and verdant Art Deco past."
In Cult of the Wind, players compete and cooperate in ritualistic multi-player human dogfights, complete with imaginary weapons, pretend explosions, and airplane noises made with their mouths. Shower your friends in a hail of imaginary bullets and proclaim, "I got you! You have to lie down," to which they respond, "Nuh-uh, I have a shield." You argue about whether or not airplanes can have shields, meanwhile some other guy does a cannonball onto your head while whistling. It's great.
