🌍 GeoSim — Rule the World

The most detailed browser-based geopolitical strategy game ever built.

You are the supreme ruler of any nation on Earth. Every decision you make has consequences that ripple across the entire planet. This is not a simplified board game — this is a living simulation of how the world actually works.

🗺️ PICK ANY COUNTRY. CHANGE HISTORY.

Choose from 150+ real nations — from the United States to Qatar, from Iran to Zimbabwe. Each country starts with realistic GDP, population, debt, military strength, ideology, religion, ethnic composition, named leaders, and political history. Pick Egypt and inherit Mubarak's legacy. Pick North Korea and threaten the world from day one.

💰 BUILD AN EMPIRE OF WEALTH

A complete fiscal system tracks every dollar:

• Set your income tax rate (10-50%) and watch citizens react — too high and protests erupt, too low and deficits spiral
• Earn corporate tax, commodity export revenue, stock dividends, tribute from economic dependents, and investment profits
• Every cost — military salaries, equipment maintenance, healthcare, welfare, debt interest, commodity imports — runs through a real government budget
• Surpluses flow into your State Treasury, not directly to GDP. You decide when to inject funds into the economy
• Run a fiscal deficit and the treasury covers it first, then you borrow. Hit 150% debt/GDP and GDP takes direct hits
• A Debt Diagnostic tool explains exactly why your debt is growing, ranked by biggest costs

State Treasury — the buffer between your income and your economy:

• Sell gold reserves for $4 trillion → treasury fills up
• Buy military from treasury, not from GDP
• Inject funds manually to time economic stimulus
• Repay debt with treasury surplus to save on interest

Full investment system — buy stakes in real global companies (Apple, Saudi Aramco, Volkswagen, Alibaba, Nestle and dozens more), trade cryptocurrency (Bitcoin, Ethereum, and others), and list your own companies on the global stock market. Sell holdings and proceeds flow to treasury, not GDP.

🛢️ COMMAND THE GLOBAL COMMODITY MARKET

15 commodities drive your economy and your military:

• Oil, natural gas, grain, fresh water, rare earth minerals, gold, silver, copper, iron ore, coal, uranium, timber, ammunition, electricity, and electronics
• Every commodity has reserves you can stockpile, domestic production, and global market prices
• Shortfalls hit stability, GDP, and military readiness — surpluses can be sold for billions
• Sanctions can block specific commodities for specific nations
• Currency weakness makes imports cost double — a collapsing Rial means grain costs twice as much as for a nation with strong money

⚔️ WAGE WAR — THE RIGHT WAY

War in GeoSim is geographically realistic:

• Land borders matter — Iran cannot teleport soldiers to Zimbabwe. You need transit rights through neighbouring countries, or you fight an air/naval-only war
• Request or threaten transit — ask South Africa for passage to attack Zimbabwe. They can agree, refuse, or counter-declare war on you
• Aircraft carriers and amphibious ships unlock global naval landings — but only on coastal nations. Landlocked countries require land transit, full stop
• Island nations like Tonga or Japan are unreachable without a carrier group
• MDP alliances auto-grant transit — your allies' territory is your highway

Full war simulation — battles, casualties, province captures, civilian tolls, equipment losses, war crimes, peace negotiations, annexation, puppet states, reparations, and regime change. Wars end through Sue for Peace with fully customisable terms, or through total military collapse.

26 provinces per major nation, named after real administrative regions. Capture them one by one. Province control determines peace terms.

☢️ GO NUCLEAR

Develop a nuclear weapons program ($50B, 3 turns) — or skip the queue and buy warheads from North Korea's black market ($1.5B each, immediate delivery). A covert transaction, officially denied.

Strike any nation on Earth from the Nuclear Arsenal panel. Guaranteed counterstrike if your target has warheads — Mutual Assured Destruction is not a dice roll, it's a certainty. Every nuclear exchange is recorded in war history with exact casualties and GDP destroyed. HR organisations issue condemnations. The UN convenes emergency sessions. International coalitions form against you.

Issue nuclear ultimatums — demand compliance or threaten to fire. Coerce enemies into ceasefires, tribute payments, or sanction lifts.

🌊 CONTROL THE WORLD'S CHOKEPOINTS

Nine maritime chokepoints can be closed or blockaded:

Strait of Hormuz (Iran, UAE, Oman) — 20% of global oil. Close it and the world pays double for energy. Suez Canal (Egypt) — 30% of container traffic rerouted around Africa. Strait of Malacca (Malaysia, Singapore, Indonesia) — 80% of China's oil imports. Bab el-Mandeb (Yemen, Djibouti, Eritrea) — gateway between Red Sea and Indian Ocean. Taiwan Strait (China, Taiwan) — 50% of global containers, semiconductor supply chains. Panama Canal (Panama) — US east-west shipping, Cape Horn detour if closed. Cape of Good Hope (South Africa) — the backup route. Close Suez AND Bab el-Mandeb simultaneously and South Africa becomes the most powerful nation on Earth. Danish Straits (Denmark, Sweden) — only exit from the Baltic Sea. Trap Russia's fleet. Turkish Straits / Bosphorus (Turkey) — Russia and Ukraine's export lifeline. NATO's most powerful lever.

Close a strait and affected major powers declare war to reopen it. Heavily affected nations hit 85% chance of immediate war declaration. Additional nations join the coalition every turn. The strait stays closed until you're defeated militarily — and even then your army gets two turns to recover before the strait is forced open.

🏛️ GOVERN YOUR PEOPLE

Healthcare — five tiers from bare survival to World-Class (5.5% GDP/year). Affects population growth, life expectancy, and stability.

Social Welfare — five tiers from bare subsistence to Royal/Nordic (5% GDP/year). Citizens remember generosity.

Bonus payments — distribute Royal Largesse to the population (+22 stability, scenes of euphoria). Paid from treasury.

Tax policy — citizens have a tolerance threshold. Exceed it and protests erupt. Drop below 15% and growth accelerates. The Statistics Bureau reports GDP per capita changes annually and citizens react with one of eight tiers of populist response.

Employment — invest in industrial parks, infrastructure programmes, national development plans. Unemployment above 20% drains stability every turn. Workers migrate between high-unemployment and low-unemployment nations.

Refugees and migrants — wars generate refugee flows, economic gaps generate migration. Admit them at the border with slider controls, naturalize them over time. Naturalized populations join diaspora communities by country of origin, shifting your religious composition and ethnic makeup. Track where every naturalized citizen came from.

🪖 BUILD THE WORLD'S GREATEST MILITARY

🌍 DIPLOMACY, INTELLIGENCE & COVERT OPS

Bilateral relations with every nation — ally, MDP, neutral, rival, or war. Relations shift based on every action you take. Bilateral scores track your relationship numerically.

Covert Operations — false flag attacks, car bombs, assassinations, disinformation campaigns, infrastructure sabotage, border incidents. Each has a detection risk and may trigger war.

Ethnic manipulation — shift the ethnic composition of foreign nations covertly.

Ethnic cleansing and mass deportation — internal operations that trigger Amnesty International, Human Rights Watch, and the UN Human Rights Council condemnations. Recorded permanently in the War Crimes Registry.

Sanctions — impose them commodity by commodity. Block oil exports, grain imports, rare earth trade.

Foreign aid — send money, military equipment, or both. Recipients thank you publicly. Relations improve.

Diplomatic statements — warnings, ultimatums, recognition, praise. Some trigger war.

UN voting — participate in Security Council sessions.

Military transit requests — formally ask neighbouring countries for passage. They can comply, refuse, or counter-declare war. Threaten them and face the same three outcomes.

International arrest warrants — issue warrants for criminals in foreign nations. Allied nations comply. Rivals refuse.

👑 LEAD YOUR NATION

Every country has a named leader with title, party, ideology, and traits. Leaders are ousted through coups, revolutions, elections, and wars. When a leader falls, they join the Ousted Leaders list — you can restore any of them to power at any time. Scroll through the full history.

Egypt starts with Hosni Mubarak (NDP, resigned 2011), Mohamed Morsi (Muslim Brotherhood, coup 2013), Mohamed ElBaradei (National Salvation Front, resigned 2013), and Ayman al-Zawahiri (Al-Qaeda, fled 1981). Restore any of them.

Six named advisors — Economic, Military, Foreign Affairs, Intelligence, Interior, and Resource ministers — give context-aware advice each turn based on your actual game state. Up to two speak per turn.

⚖️ JUSTICE, CRIME & HUMAN RIGHTS

Prison system with arrest, sentencing, and execution. Charge criminals with treason, corruption, terrorism, war crimes, political dissidence, espionage, or sedition. Set sentences from 5 years to death.

12 criminal event types fire automatically — embezzlement, coup plots, journalist arrests, sanctions-busting, POW massacres, foiled terrorist attacks.

Pending criminals queue — perpetrators appear with one-click sentencing buttons.

International arrest warrants — issue them against foreign nationals. AI nations comply or refuse based on your relationship.

War Crimes Registry — the top 10 most severe crimes committed globally, ranked by severity. For each crime, choose to condemn diplomatically, threaten war, or declare immediate humanitarian intervention with the crime as legal casus belli.

Three human rights organisations with distinct editorial voices issue condemnations whenever violations occur:

• 🕯️ Amnesty International — urgent and emotive, focuses on individual victims
• 👁️ Human Rights Watch — investigative, cites specific numbers and legal violations
• 🇺🇳 UN Human Rights Council — diplomatic but firm, references international law

Rogue AI states — authoritarian and theocratic nations spontaneously commit crimes every few turns, giving you opportunities to intervene.

🏦 CURRENCIES & FOREIGN RESERVES

Every nation has its own currency with a strength rating (0-200). Eurozone nations all use the Euro. The strength is driven by your stability, debt ratio, trade balance, sanctions, wars, treasury size, and foreign reserve holdings.

Weak currency = expensive imports. At strength 50, every commodity costs twice as much. At strength 30, three times. A strong currency gives you a 20% import discount.

Foreign reserves — hold dollars, euros, and yuan as a buffer. Buy reserves when strong. Spend them to defend your currency when it weakens. When reserves run out, you can't defend — the currency collapses.

Global Currency Rankings show every nation's currency strength and import multiplier. Watch Iran's Rial collapse under sanctions. Watch Norway's Krone strengthen as oil exports surge.

📰 THE WORLD TRIBUNE

Every turn, The World Tribune publishes a newspaper using genuine editorial prose — no copy-pasted event log text. Five distinct article templates per story type, rotating randomly, written in the voice of a real international newspaper:

"GUNS OF 2031: IRAN AND EGYPT AT WAR — The world woke to news of war. Iran's armed forces crossed into Egypt in the early hours, marking the opening of what analysts fear could be a prolonged and bloody conflict."

"BOOM TIMES: QATAR ECONOMY SURGES TO $7.2T — Citizens are feeling wealthier, with GDP per capita now at $93,000. Analysts credit disciplined fiscal policy and commodity exports. Foreign investors are taking notice."

"CONDEMNED BY WORLD COURT OF OPINION — The arrest of a prominent dissident on charges of sedition has become a rallying point for international human rights campaigners."

War declarations, battles, nuclear tests, debt crises, executions, refugee flows, military acquisitions, economic swings, diplomatic ultimatums, and player spotlights — all written as real journalism.

🌍 A LIVING WORLD

AI nations are not passive. They declare wars, form coalitions, go bankrupt, experience coups, commit crimes, send humanitarian aid, naturalize refugees, and build nuclear weapons. Authoritarian states spontaneously crack down on dissidents. Great powers respond to threats. Rogue states cause crises you can choose to ignore or intervene in.

Global Humanitarian Digest — every turn, a ranked list of the top 10 countries most in need of aid, scored by shortage severity. Plus a consolidated aid delivery summary showing which nations helped whom.

Statistics Bureau — annual economic reports for your nation comparing GDP per capita, with eight tiers of citizen reaction from protests to celebrations.

Newspaper archive — last 10 issues saved, browsable by year.

War history with full records of every conflict — duration, casualties (soldiers and civilians), nuclear exchanges, territorial changes, annexations, reparations, and regime changes. The record persists forever.
