Game Projects
Tabletop and digital game projects — tools, generators, and game frameworks.
A procedural star system and world generator built as a Progressive Web App (PWA). Designed for tabletop sci-fi RPGs, it produces scientifically grounded systems using recursive logic and dice-based mechanics.
The core philosophy is simulationist and modular: stellar formation, planetary placement, habitability, and civilisation development are each broken into separate procedural systems that feed into each other.
Key Features
- Four-level hierarchy — Stars → Planets → Moons → Surface detail and artificial habitats
- Orbital stability — Mutual Hill Radius calculations and Rule of Five constraints prevent physically impossible planet placements
- Habitability waterfall — Multi-step algorithm evaluating mass, orbital position, composition, hazards, atmosphere, and temperature in sequence
- Civilisation layer — Population, development, inequality modelling, and technology level integration affecting economic output
- Snow line and habitable zone calculations for each star type
Status
Active development. Current spec: Draft 2.1 (260222). See Revision Notes 260222 for planned changes.

Traveller Character Generator
Fork of an existing open-source Traveller character generator.
Open PVE Card Game System (OPCS)
An open-source, cooperative card game framework where players face scenarios they design instead of each other. Cards are proxy-friendly, scarcity-free, and skill-driven. Power comes from strategy, coordination, and accumulated consequences — not purchases, rarity, or power creep.
