Ratnarok: Building an AI-Driven Tabletop RPG

What happens when you combine AI with tabletop RPGs? You get Ratnarok — a web-based RPG where players are heroic rats in a post-human world, powered by AI-driven narrative.

Three Game Modes

• Solo Mode — Fully procedural AI-generated adventures with Gemini driving NPC dialogue, quests, and world events
• Semi-Guided — AI + optional human Game Master collaboration
• Free Tiles — GM-defined sandbox mode for creative freedom

Technical Highlights

• 8 character classes, 8 origins, 5 biomes, 20+ enemies
• Complete combat engine with leveling, inventory, and shop system
• Real-time multiplayer via WebSockets
• Persistent characters via Supabase
• Complex prompt engineering for narrative consistency

Ratnarok demonstrates that AI can enable entirely new genres of interactive entertainment — not by replacing human creativity, but by scaling it.
