Thinking about a cohost centric queer map jam, bring your fav engine and make a short 1 minute to play through map.
And you don't have to be queer but it might help, who knows, the universe is a strange place
Oh gosh I'm not good at mapping but this would be a great chance for me to get back into doom map stuff, or to try out Quake mapping or something.
Or something more modern but still fun and playful, like building a Minecraft adventure map
