United Kingdom is a P5 nuclear state, financial-services powerhouse, and in SFC Nations it's run end to end by the AI as the United Kingdom Coalition-AI. Its regions play as AI-Kingdoms, and the major cities inside them are titles you can claim — "Your Name - Kingdom of London". Set your tax rate, pick a government, build infrastructure, trade, and see how far you can push a Europe power. Free, in your browser, no download.
United Kingdom is a P5 nuclear state, financial-services powerhouse. In SFC Nations that shapes everything — your neighbors, the alliances that want you, the resources you spawn near, and the wars that come knocking. Playing a Europe power isn't the same as playing a superpower on the other side of the map, and the game reflects that.
Set your tax rate, pick a government type, hire generals, build out infrastructure, and manage happiness. You're not just clicking "attack" — you're running a budget, deciding when to fund military versus infra, negotiating trade deals, and choosing alliances. Every decision has a tradeoff a real leader from London would recognize.
Trade with 8 AI nations and real players. Join 12 AI alliances. Send espionage missions. Defend against weekly AI campaigns. Climb global leaderboards. No paywall, no premium tier — the whole game is included whether you play as United Kingdom or any of the other 194 nations available.
Create a free account, name your nation, then drop your capital on or near London on the real-world map. From that moment United Kingdom's starting treasury, citizens and resources are yours to run.
No. Landing on this page seeds your Europe location and flavour, but the name on your flag is entirely yours — call it United Kingdom, a historical variant, or something invented.
Your immediate Europe neighbourhood includes Croatia, Cyprus and Bulgaria, plus every real player who has anchored nearby and the 8 AI powers that operate worldwide. Proximity matters for trade routes and for who notices when you mobilise.
United Kingdom is P5 nuclear state, financial-services powerhouse. That shapes which resources spawn near you, which alliances court you, and how much room you have to manoeuvre before a bigger Europe power decides you're worth attacking.
Collect taxes every 24 hours, keep happiness above the crime threshold, and don't overbuild military before your infrastructure can pay its upkeep. That order of operations decides most early United Kingdom runs.
Yes. Rankings are driven by population, treasury, technology and military — not by real-world GDP. A well-run United Kingdom regularly out-earns a badly-run superpower, and the leaderboards reflect exactly that.
Free to play. No credit card. One nation per player.
United Kingdom is AI-run from top to bottom, the same way the United States Coalition is. It presides over 4 AI-Kingdoms and 24 claimable city kingdoms. Pick a kingdom, pick a city, and your ruler name goes in front of the title.
