Robin Sloan smushes the video game Fortnite Battle Royale together with Liu Cixin’s Three Body Problem trilogy and produces a perfect example of game theory, cooperation, and the prisoner’s dilemma.
Based on my experiments in the laboratory of Fortnite, I think Liu Cixin is wrong. Or at least, he’s not entirely right. Fortnite is more Dark Forest theory than not, and maybe that’s true of the universe, too. But sometimes, we have a lever against the vise of game theory, and in this case, it is a single bit of communication. I mean “bit” in the programmer’s sense: a flag with a designated meaning. Nothing more. My heart emote didn’t make Fortnite cuddly and collaborative, but it did allow me to communicate: “Hold up. Let’s do this a different way.”
