The game generates a unique country for you with detailed characteristics (culture, economy, crime rates, etc). Each turn, you face natural events like protests, sanctions, or disasters, and can respond with any policy decisions via free-form text. The AI then simulates complex ripple effects - for example, a policy promoting domestic oil might affect your CO2 emissions, international trade relations, and even traffic fatality rates.

Technical details: - Built with Next.js + FastAPI - Uses OpenAI's reasoning models (o1 and o1-mini) to handle simulation - Structured as a multi-agent system where o1 orchestrates key changes and o1-mini handles detailed updates - Everything including the country flags is AI generated
