01 The MMO economy
Multiplayer here does not mean seeing other players. It means selling into the same markets they sell into, and buying what they also need. Your competitor does not have to shoot you to affect you: they can consume the input you needed, expand capacity before you do, flood a market, or create demand somewhere else.
Buyers want more hosting than the region's data centers can sell. The auction clears high, and every bid says so.
A player, or an NPC company reading the same price, orders racks. The project buys construction crews and equipment on their own markets.
Crews are booked, steel and equipment tighten, electricity rises where the hall is going up. Prices move three markets away from the decision.
Weeks later the racks come online. Hosting falls; the fleets that waited buy cheap; the hall that overpaid for its crews sells at a loss.
The shortage is now in compute, or in the other region. Nobody wrote that. Where is it now?
Bids and asks meet in a uniform-price call auction. The clearing price maximises trade; when one side is under pressure, that side gives way. Twenty markets, fifteen products, from electricity and labour to chips and food.
Selling consumes real output. A data center without power produces no hosting; a fleet with nobody hosting in its region produces nothing at all. Shortages hit specific counterparties.
Every cent moves through one ledger. Two banks lend what they have, a default costs the lender, and a company that runs out of everything goes to a public receiver that sells its assets on.
02 An economy that exists without you
03 Persistent worlds
You are not creating a save game. You are entering a world that may already have years of history: its own companies, its own NPC population, its own prices, its own speed. Some run at one day a few seconds; some are slow; some are experiments that may be reset.
STANDARD WORLD
Design preview: live figures appear here when the page is served next to the game.
04 Your company
You start with a founder's stake and a public startup loan, enough for a first plant, a first hall or a first fleet. Everything after that is a decision with a price.
Every price with its history, what is online and what is being built, the share that went unsold, and where buyers are waiting with nobody to sell to them.
Order a project and wait out its lead time, or buy a failed rival's plant from the public receiver. The cost sheet says what it earns per day before you commit.
A public development bank and a commercial one live in the world. Your leverage, coverage and payment record decide what they lend and at what rate.
Your company trades every day whether you are there or not. You set the standing orders: minimum selling prices per market, maximum buying prices, how much of your capacity to run.
Fixed-price supply for months, firm or best-effort, delivered before the spot market. Your delivery record is public and buyers price it.
Mothball a hall, move an asset to the other region, repay early, wind a company down and start another. Grow, or fail and learn why.
Player and NPC companies run on the same rules and the same services. The world exists before you arrive, and it keeps going when you leave.
05 In play
Captures of the alpha build, September 2026. The interface keeps moving.
06 Built by one developer, in the open
World Economy is an independent project built by one person through continuous development and playtesting. The simulation is playable today. The alpha exists to find out what happens when real players enter the economy.
Every development loop is written up with the code: what it tried, what broke, what the economy did, with the simulation's own numbers. The economy runs headless first, years of a world in minutes, measured on several seeds before any change is kept. What changes for players is announced in the game's news.
If something is confusing, unbalanced, broken, or unexpectedly fun, I want to know. There is no community server or mailing list yet; a feedback channel inside the game is on the list, and this line will point to it when it exists.
Now
The free public web alpha: persistent worlds on one server, playable in the browser, balanced loop by loop.
Next
More players on more worlds, the economy validated with them, the balance read from what they do, a feedback channel in the game.
Later
Larger public playtests, then Steam. The web alpha comes first, and it is free: no purchase, no subscription, no microtransactions. How the game evolves beyond the alpha is not decided yet.
