How it plays

Steering nations across diplomacy, economics, and warfare at historical scale across multiple countries and the entire war theater is the primary gameplay loop. Combat and strategy unfold in real time but can be paused to queue orders and plan, a defining Paradox grand strategy convention. Real-time command of economies, armies, and battle plans, with pause for strategic deliberation, defines moment-to-moment play.
