The world from 2000 to 2075
Lead a nation through 75 years – from the turn of the millennium into a future of fusion, AI and climate change. Alone, with friends or against each other. Right in your browser.
The depth of Hearts of Iron, Victoria and Millennium Dawn – in one continuous campaign from 2000 to 2075. Economy, trade, diplomacy and military interlock. Every value explains why it is what it is.
The same game evolves from diesel tanks and large power plants to drone swarms, AI data centres and fusion power – without switching scenarios.
The financial crisis comes because debt and speculation have actually built up – not because the calendar says 2008. Stricter regulation softens the blow.
Co-op and multiplayer with 2–16 humans plus AI, over several evenings, via invite link right in the browser – crossplay with Steam.
Oil from the Gulf, gas through pipelines, manufactured goods through the Channel and the Mediterranean. In the game, each of these lines is a flow of goods in the simulation – recalculated every week.
Every flow out of the Persian Gulf passes this one strait. Whoever controls it holds leverage over markets on three continents.
A nation escalates and closes the passage. Flows are rerouted or break off, stocks run down, transport gets more expensive.
The crude oil index rises. Refineries in Europe throttle, transport costs climb, factories report their limiting factor: fuel.
Thousands of kilometres away, stability drops. The “Why?” tooltip shows the full chain of causes – all the way back to the blockade. That is SOVEREIGN.
In the codex: trade & chokepoints →Ministries automate the administration. You decide the strategy.
World market with weekly prices, sea lanes, pipelines and chokepoints from Gibraltar to Hormuz. Embargoes act through real routes.

Population groups, production chains, budget and debt. Every factory shows its limiting factor.
Conflicts begin as crises with an escalation ladder. Alliances, sanctions, conferences and spheres of influence.
Equipment in generations, fronts, supply over the same network as trade. Deterrence from the start.
A tree as a timeline: researching ahead costs more, falling behind gets cheaper through diffusion.
An automatically written history book of your game. The map itself: relief, rivers, country names that follow the borders.
