RPG Ruleset Optimized for LLM DM play

Stevie Lee

First Post
I have spent about six weeks developing and optimizing an RPG canon/ruleset and stress testing it against ChatGPT and Grok. ChatGPT was dropped (too many limitations w/r to memory and context awareness), so I have focused on Grok. It is pretty amazing now, and the remaining issues are systemic LLM issues that will only be resolved with dynamic context aware access to persistent memory. I have no awareness of the online community, but would like to drop a copy of this for folks to try out and was wondering if this community was a good place and where would be an appropriate spot? BRIEF SUMMARY:
STARFARER is a hard sci-fi RPG canon designed for AI-assisted play (e.g., with LLMs like Grok). It emphasizes realistic physics, consequence-driven decisions, independent crew dynamics, and procedural generation with limited look up tables for compression. Players start on Earth, then after a DiscoveryArc (unique) find their way to becoming a junior crewmember on a neutral starship in a post-2025 solar system, managing missions, promotions, and resources while uncovering deeper mysteries—potentially involving your Chow Chow companions, Akira Bear and Ravynir.

Core Themes

Realism First: Vacuum combat, recoil momentum, sensor limitations, propulsion constraints—no plot armor or narrative shortcuts.

Crew & Companions: Independent NPCs with personalities that evolve; mythic-yet-grounded dog companions with tactical roles.

Immersion: All characters defined by personality parameters and deep descriptions. Play is player driven open free text, with no multiple choice, and incredibly immersive.

Progression: Merit-based promotions, ship transfers, faction alliances—decisions cascade into wars, losses, or triumphs.

AI-Optimized: Structured schemas, procedural tools, and state-tracking for long campaigns.

Quick-Start
Player Setup: Provide a 1–4 sentence 2025 Old Earth backstory (profession, ties, etc.). Choose Y/N for immediate Chow companions.

Starting Point: Neutral starter ship (e.g., 80m Corvette-class freighter). Junior billet (e.g., Scout/Rifleman). First obligation: 1–2 missions.

Base Game Loop: View job board for billets you qualify for (post-obligation), vote on mission contracts with crew, execute missions with realism enforcement. Track time, inventory, relationships. Enlistments are by a set number of completed contracts (2 to 4 typically), then you can transfer. THIS IS THE STARTING POINT: You can do whatever you want. I've bought my own ship, terraformed Mars, been commissioned in a faction military... so the base game loop is just where it all begins (it is fun though)

LLMs: Use procedural generators for ships, sensors, weapons.
Output DYNAMIC UPDATE blocks for persistence.
Arc Reset: Use the template provided with STARFARER to copy-paste state at resets.
