"History is not written in stone"

The old empires are cracking. Thrones wobble, borders bleed, and the century is waiting for someone bold enough to seize it. In Ruler of Empires you take command of a nation and bend the flow of history to your will — hold together an empire the history books say should fall, or tear up the map and forge a new order from the ashes.

Ruler of Empires is a turn-based grand strategy game where you conquer a living world, master combined-arms warfare, and build a legacy that outlives every campaign.

Conquer a Living Map

No abstract tiles — a hand-crafted world of provinces with real borders, coastlines and terrain. Advance your front line, seize the chokepoints, and watch your nation's colors spread across the continent one province at a time.

Combined-Arms Warfare

Wage war on three fronts. Command infantry, armored cars, tanks and artillery on land; destroyers, cruisers and battleships at sea; fighters, bombers and carriers in the skies. Every unit grows stronger through research — the green recruits of today become the war machine of tomorrow.

Research & the Society Tree

Climb a branching tech tree across land, naval and air doctrines — but firepower alone won't win the century. Advance your Society to unlock the deepest tiers of progress. A nation that only builds guns will always be outpaced by one that builds a future.

A Ruler's Legacy

No campaign is ever wasted. Earn prestige and medals to unlock permanent upgrades in the Ruler's menu — deadlier armies, a stronger economy, tougher defenses — that carry forward into every new game. Rise from warlord to living legend.

Commanders & Medals

Appoint commanders to your armies and turn good troops into unstoppable ones with powerful buffs. Win battles, earn medals, and grow your officer corps into the backbone of your war effort.

Build Your War Economy

Cities, industry, research centers, air bases, land and coastal forts, anti-air — every province is a choice. Juggle money, industrial output and research to out-produce, out-tech and out-last your rivals.

Rewrite History

The past is only a starting point. Rescue a nation destined for collapse, flip the balance of power, or raise a single flag over the entire world. Every campaign is a new "what if" — and how it ends is up to you.

Nations, Ambitions & Victory

Choose from distinct nations, each with its own flag, colors and starting position. Chase your ambitions and race toward multiple paths to victory — from regional dominance to total world conquest — against AI opponents that play to win.
