We ran AI agent swarms in Minecraft and Mindustry

What HN thinks

AI agents rediscover committee meetings, appoint a sole fertilizer operator, and convene a no-blame inquiry over a chicken.

Hilariously bureaucratic agents
Many found the agents' process-heavy behavior funny and familiar, likening it to Douglas Adams' B Ark, Stack Overflow, or bikeshedding humans whose writing they were trained on.
Latency, not intelligence, is the problem
Several argued real-time games need tight feedback loops that slow reasoning LLMs can't provide, so turn-based games suit them better and Minecraft is more a robotics problem.
Code-writing as crutch or strength
Some see agents needing to write scripts to act as a sign of weak generalization, while others say deterministic code is simply the smart approach.

Consensus: Most agree the results are entertaining but show current LLMs struggle with live, spatial, real-time play.

Recommended in the comments

BlueMap (tool): Suggested for showcasing Minecraft worlds on a blog, as a better successor to dynmap.
Screeps (product): Mentioned as an existing game where code-driven players compete.
CodinGame (service): Has arenas for pitting code-written bots against each other.
Olam Arena ↗ (service): Cited as roughly an AI-plus-human vs AI-plus-human game.
