One of my longest-standing "maybe someday" projects has always been trying to make an as-faithful-as-possible recreation of the titular ttrpg from one of my favorite modern creepypastas, Escape from Terminus.
I haven't really given it much thought beyond the "I wanna do this someday" level until recently, but I kinda have some ideas about it.
The end result would be more of an art-project than an actual thing you'd probably want to olay, it should be playable but it's explicitly meant to be an extremely archaic ttrpg from 1965 and The text explicitly mentions that Rolemaster was a "simpler" game to play by comparison (although this might be a tongue-in-cheek remark from our point-of-view character and not completely literal) so it should be overcomplicated, overengineered, and extremely cumbersome to actually play.
It should also eschew not only modern design sensibilities, but also a lot of *traditional* design sensibilities. Since it's supposed to be a game that predates the original edition of D&D by almost a decade, any concepts invented by D&D should be either entirely absent (preferrable), or visibly independently invented from first principles.
It should be almost entirely table-driven, with most actions resolved by rolling on a table, and probably with most tables directing you to a different table. The text explicitly mentions "hundreds" of tables modified by bonuses from everything from surrounding rooms to recent player actions, so that's going to be fun to figure out.
The creepypasta mentions that the game uses a 6d7 roll plus a coin flip to generate results with an "inverted bell curve" probability distribution. My first idea for this was something like rolling a 6d7 and flipping a coin, on heads keep the highest result, on tails keep the lowest result, but I realized this was probably going to be hard to work with, because it would result in the roll *very rarely* showing anything other than 1 or 7, and a probability space of 1-7 is kind of limiting for a table-driven game. So my idea rn is doing the same but instead keeping the 3 highest or 3 lowest dice depending ok the coin flip, with maybe some special effects for special results such as matching numbers (1 1 1, 2 2 2, etc.) and consecutive numbers (e.g. 1 2 3)
The thing that I think is going to be hardest to pull off is the spawning of the "exit hex", the story explicitly mentions that there are strategies for maximizing the chance of generating it, but that the reason no one has been able to do it is because any attempt to optimize for it also increases the chance of intervention from a sabotaging presence that the game's play culture has collectively personified (and probably unintentionally brought into existence by themselves through decades of houserules) as "the minotaur".
This necesitates that 1) the chance of spawning the exit hex is influenced by a complex web of factors affected by player actions, and 2) that the same web of factors also influences the "minotaur"'s activity.
Idk just putting some ideas down, probably a project that would take me a few years if I actually decided to commit to it, but I'm at least trying to outline the shape of what I'm aiming for.
Tables should probably have overly technical names such as "Ceiling integrity index", "Internal obstruction matrix", "Door hinge noise severity" or "Footwear degradation speed"
Actually if anyone's got ideas for table titles that would be fun. The higher grade of implied needless granularity the better. Shit like "vermin migration table" or "light source reliability" or "writing instrument failure" or "mold growth severity" or "water contamination index"
Alright, let me take a shot of this because I fuckin love Escape from Terminus, one of my favorite scp tales(along with the tale 1914 and The Foundation eats Babies) so me and my friend shot off some ideas for table titles.
Brick Wall Erosion Level(not to be confused with other type of wall erosions, would probably effect how legible a note written on it is)
Cave Material Type(limestone has different properties than Granite!)
Wild Animal Intrusion Probability(Probability of an animal from outside the Labyrinth, being inside the Labyrinth)
Cistern Water Clarity (How clear the Cistern water is, directly effects or is effected by, water contamination index)
Corpse Decay Stage (self explanatory)
Surprise Defecation Index (if you shit yourself in fear or through stomach problems)
Malaria Progression Stage (Malaria is a real killer if you end up with it)
Cruelty Level(Self Explanatory)
Panic Attack Chance(chance to have panic attack, cause shit scary)
Iron Breastplate Rust Progression(How rust progression effects an iron breastplate)
Scream Volume as Affected by Distance SVAD (how the volume of a scream is effected by the distance from said scream)
