Vibias Market - D&D Economy Simulator

A real-time market simulator designed for Dungeons & Dragons campaigns, bringing dynamic economics to tabletop gaming with realistic supply and demand mechanics.

Project Overview

Vibias Market transforms static D&D item pricing into a living economy. Game masters can create immersive marketplaces where player actions directly impact prices, availability, and merchant relationships.

Key Features

Dynamic Pricing Engine

• Real-time price fluctuations based on supply and demand
• Regional variations reflecting local resources and trade routes
• Event-driven market crashes and booms
• Seasonal adjustments for agricultural goods

Multi-User Support

• Simultaneous access for GM and players
• Player trading impacts global economy
• Merchant reputation system
• Guild membership benefits

Item Database

• 500+ pre-configured D&D items
• Custom item creation tools
• Rarity-based availability
• Magical item auction system

Technical Implementation

Built as a web application using:

• Frontend: React with TypeScript for type-safe development
• Backend: Node.js with Express for API services
• Database: PostgreSQL for persistent storage
• Real-time: Socket.io for live market updates
• State Management: Redux for complex economic calculations

Market Mechanics

Economic Simulation

The system simulates realistic market forces:

• Base prices adjusted by local availability
• Bulk purchases increase future prices
• Rare items trigger bidding wars
• Economic events affect entire regions

Player Impact

Every transaction matters:
