Neural Networks of Carcosa

Something I did for fun over the weekend:

  • Found a workbook for easily creating a text-generating neural network:
  • Took a plaintext dump of the hex contents from LotFP's Carcosa.
  • Massaged the text to make it a little better for neural network processing (make everything lowercase, remove punctuation, remove numbers, etc.)
  • Trained the neural network against the text (ran 50 epochs worth of character-level training)
  • Took the resulting model and generated some sample text using the workbook's default settings of "1 very unexpected token, 1 unexpected token, 2 expected tokens, repeat" to ensure the model doesn't try to exactly replicate the original text.


I tried to create an AI that can auto-generated Carcosa-like hex descriptions. The results are... kind of weird. The neural network was being trained letter-by-letter rather than word-by-word, so there's no guarantee it won't invent its own, gibberish words. But the results are interesting in a Jabberwocky, nonsense-that-kind-of-makes-sense way. This is my first pass at this (and my first time doing anything with neural networks), but I think this could be tweaked into something useful as an idea generator.

I'm kind of wondering what would happen if I trained the neural network on Carcosa + Alice in Wonderland + Dracula. Could it generate at least a few useful locations for my A Red & Pleasant Land campaign?

Dungeon in a Cigar Box

This has popped up in several pictures I've posted.

This is the dungeon-in-a-cigar-box that I built. Absolutely nobody asked about this, but I'm going to write about it anyway.
Inspiration for this came from this CRIT KIT Kickstarter that I missed out on:

Stumbled upon that a couple months back and thought it looked cool. Portable box that functions as a dice tray, dice & mini storage, and modular dungeon. Thought it would be a fun project to try building myself.

Additionally, you already know I love some Dragon Warrior.

Thought I'd make my dungeon floor and walls resemble that.
Bill of materialsI picked up most of this stuff at Michaels. Any arts & crafts store likely has comparable items.

Wooden cigar box: & stick red felt: couple sheets o…

A Simple Resource Management System for Into the Odd

Rules without the commentary available here.

My mind is still on resource management systems. 

Into the Odd (ItO) doesn't have one and, to be honest, doesn't need one. Plenty of tension to be found via description rather than tracking individual rations. ItO is lightweight, fast, and runs great if you simply assume that, as written, the expedition always has food, water, light, camping & climbing equipment. 

So why bother with managing resources? 
Character customizationLike with Ben Milton's new Knave (, I like the idea of a character's role being determined by what kind of equipment they are carrying. Want to be a "fighter" in a classless system like ItO? Carry large, powerful weapons and wear armor. Want to be a "magic user"? Carry lots of Arcana (or spellbooks). A "specialist" (to use the LotFP term)? Carry lots of tools, poison vials, flashbangs, etc.

But customization like this works best if there is a l…

Dragon Warrior and How I Discovered Into the Odd

Continuation from Part 1

So I already talked about my quest to run dungeons for my players that feel as tense to them as Dragon Warrior's dungeons did to me. I talked about trying a game, Torchbearer, that had systems built around emphasizing the things I thought that tension was about: the importance of light, limited resources, dwindling life. And about how I eventually found more of my mental energy going to managing those systems than to my campaign.

Let's take a detour back to Dragon Warrior / Dragon Quest.

More specifically, let's look at combat in Dragon Warrior. It's pretty basic. Only 4 actions to choose from: FIGHT, RUN, SPELL, ITEM. Seemingly worlds apart from the "free to try anything, and your referee will come up with a ruling" land of OSR and other tabletop RPGs. Even by comparison to other JRPGs, it looks like a limited and kind of boring list of choices. Compare it to, say, Final Fantasy 5, with its huge system of jobs, skills, summons, differ…
