Context

Tabletop RPGs require significant Game Master preparation — worldbuilding, NPC creation, encounter design. Most digital RPG tools either automate mechanics or narrative, but rarely both in a cohesive experience.

Approach

Built a web-based RPG with three game modes:

Solo — fully procedural AI-generated adventures with Gemini-driven NPCs

Semi-Guided — AI + optional human GM

Classic — traditional rules with digital tools

Features 8 character origins, 8 classes, 4 core attributes, and full game rules documented across 12 specification docs. Character data persists via LocalStorage.

Outcome

Working RPG system with complete rules engine, character creation, and AI narrative generation
