LLM the Warbot: "Misuse of 'their' detected!" |
Some people train large language models to write poetry or give dating advice.
I trained one to run Gamma World 3rd Edition.
Because if we’re going to let AI take over the world, it might as well start with the irradiated wasteland of post-apocalyptic roleplaying.
🎲 What It Is
I created a custom GPT trained on the third edition Gamma World rules, using two searchable PDFs that I legally purchased from DriveThruRPG. It acts as a succinct, rules-savvy AI referee that:
-
Answers game mechanics questions quickly
-
Cites sources when possible
-
Offers elaboration only if requested (because verbosity is a mutation)
Whether you're a mutant plant trying to figure out how radiation affects your chloroplasts, or a GM wondering how many hit points a warbot should have, it’s got you covered.
🧠 How It Works
The GPT uses a simple guiding prompt:
“You are an expert in Gamma World 3rd edition rules. Cite your references as much as possible. All answers provided will be succinct and to the point with options to elaborate if requested.”
In other words, it doesn’t ramble. It doesn’t argue. It just tells you what the rules say—and where to look. Think of it as the Oracle of TSR, minus the sarcasm (unless you enable that setting).
💬 Sample Output
Here’s a real query I gave it, with its response:
Q: What happens when a mutated human passes through a radiated area?
A: In Gamma World 3rd Edition, a mutated human typically makes a Constitution (CN) check when passing through a radiated area. Failing the check can lead to:
Temporary effects like nausea, fatigue, or attribute penalties
Unexpected mutations if the exposure is extreme or repeated
Long-term damage, such as permanent attribute loss
The specifics (like radiation zones, mutation rolls, or saving throws) are detailed in the Gamma World Referee’s Screen and Mini-Module, not the core box set. Let me know if you’d like a breakdown of those rules.
That tone—efficient, informative, and option-driven—is exactly how the GPT is designed to respond. You can treat it like a pocket rules lawyer that doesn't talk over the players.
🔐 Why It's Not Public (Yet)
For copyright reasons, the GPT remains private for now. It's not designed to replace the books—just to help me use them faster and more effectively during sessions. If you own the same PDFs, it's easy to recreate the experience by uploading them to your own GPT and using the same prompt.
I’ll be working on a public-friendly version soon that doesn’t rely on citations or proprietary material. Think “mutated GM assistant” rather than reference librarian. When it’s ready, I’ll post it here as a follow-up.
☢️ Why Gamma World?
Because Gamma World is chaos in a can—random mutations, rusty tech, absurd scenarios, and rules that occasionally implode on themselves. It’s the perfect sandbox for storytelling, and it made total sense to hand part of that chaos over to a machine trained to embrace it.
More weird AI projects coming soon.
The apocalypse, after all, is a collaborative effort.
