What problem does it solve? Game economies fail when currency faucets and sinks are unbalanced, monetization feels exploitative, or inflation spirals out of control. This Skill provides a structured methodology for designing, modeling, and stress-testing in-game economies before they reach players. ## Core Features & Use Cases - Currency Flow Architecture: Maps faucets, sinks, and currency pools with quantified flow rates per player archetype, including dual-currency and multi-currency system design. - Economy Simulation & Health Metrics: Builds stock-flow models, Monte Carlo simulations, Gini coefficient tracking, and inflation projections across 1-12 month horizons. - Monetization Design & Ethics Audit: Evaluates premium, F2P, cosmetic-only, and battle pass models against a dark-pattern checklist and regulatory landscape (Belgium, China, EU). - Use Case: When designing a roguelike with a persistent upgrade currency, use this Skill to model earn rates for casual versus hardcore players, design aspirational sinks, and verify the free-player experience remains viable. ## Quick Start Ask the assistant to design a dual-currency economy model with faucet and sink flow rates for your game's core loop.
