Oh my gosh this sounds really fun.
Are programs allowed to have either a way to differentiate themselves from each other (like one program gets a 1 and the other gets a 0 for each game) or a source of randomness? Because otherwise it doesn’t seem possible to cooperate with yourself.
It would be so cool if someone organized a game of this here or something…
Maybe references could be the votes. Like, if someone links an old post by someone else in their post or comment, every upvote on the new post could turn into “stock” votes on the old post, or something.
