Tabletop and digital game projects — tools, generators, and game frameworks.

Mneme World Generator

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.

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.
