  "summary": "The guns of September. Lead a major power through the greatest conflict in history.",
  "worldBackground": "It is early September 1939. Germany has just invaded Poland, and Britain and France have declared war. Europe stands on the edge of the largest conflict the world has ever seen. The Axis powers — Germany, Italy, and Japan — are pressing their advantage across Europe and the Pacific, while the Allies — Britain, France, the Soviet Union, and a still-neutral but industrially immense United States — are marshalling their strength.\n\nThe balance of power is delicate. Germany's army is the most battle-hardened force on the continent, but its resources are finite and its flanks exposed. Britain commands the seas but is an island nation. The Soviet Union has a vast army and deep territory but a fragile industrial base. The United States has unmatched economic power but is geographically isolated and politically divided over entry into the war.\n\nYou are the head of one of these nations. Every decision you make — military, economic, or diplomatic — ripples across the world and reshapes the map, the alliances, and the fate of hundreds of millions.",
  "simulationRules": [
    "Serious, historically-plausible tone; write like a war correspondent and a policy analyst combined.",
    "Prefer gradual change: 1-4 meaningful events per turn, never a single decisive world-ending event.",
    "Respect existing borders unless a war is declared or a decisive military shift occurs.",
    "No single nation may instantly dominate the world; power shifts are incremental.",
    "Respect the player's chosen nation's resources, manpower, and geography.",
    "Diplomacy can shift relations over time but rarely reverses a declared war in one turn.",
    "Keep stat values (military, economy, stability, population) between 0 and 100."
