Frustrated by endless video lectures, a solo developer launched Core MBA, a text‑driven business simulator that lets users read a concept in five minutes and immediately test it in a hostile market. Built with React 19 and TypeScript, the platform replaces passive watching with interactive strategy execution.

The heart of the system is a deterministic economic engine coupled to a generative AI validation layer. A custom `useMarketEngine.ts` hook runs a discrete‑event simulation, solving equations each cycle—including an Ad Fatigue formula that enforces diminishing returns. State logic embeds the Theory of Constraints, capping employee output and linking excess demand to cash loss.

Lesson text streams into Gemini Flash, which generates on‑the‑fly Combat Cases that the AI grades against principles like LTV/CAC. Successful cases award virtual capital that fuels the Market Engine; bankruptcy triggers an Advisor heuristic that points users back to the missed lesson. The creator seeks feedback on content density, AI accuracy, and economic balance.
