NationFall is a browser-based grand strategy game that opens in a tab — no account, no install, no launcher. Take command of any of 206 real nations on a live world map and steer it through history-grade scenarios, from the 1939 outbreak of WWII to a hypothetical WWIII in 2026. Every country is a live actor. AI nations pursue their own agendas — forming alliances, declaring wars, suing for peace, collapsing into civil war, and reacting to your every move. Win with tanks, or win without firing a shot: blockade sea lanes, bomb factories, sanction aggressors, or build a web of resource-dependent client states until the world bends to your economy. Play it your way — turn-based strategy, real-time with a configurable clock, or fully autonomous simulation mode where the entire planet fights, allies, and rebuilds while you watch history unfold. An optional machine-learning AI layer learns your patterns across sessions, remembers grudges, and tunes itself into a personal rival. Built for people who read the news and think about how power actually works.
