What is Space Tycoon?
A free, browser-based space MMO with no combat. It is a space economy game first: one shared live market for everything, real supply chains, hardware you have to manufacture, and corporations as the end-game. It runs as a live-service world on a hard-science 22nd-century solar system, fed by real launches and real space weather.

The idea
Most space games are about ships. Space Tycoon is about balance sheets. Every price is set by supply and demand on one global market; mass extraction depresses a commodity, a procurement drive lifts a service. Logistics cost money — delta-v, transit time, storage. Orbital slots, high-grade deposits and belt corridors are finite and contested. Profit and loss are visible per building, per location and per corporation, because that is where the decisions are.
Hardware is manufactured, not conjured. Structural beams, satellite buses, life-support packs and fusion cores come out of fabrication facilities — on Earth, in orbit, on the Moon and Mars — built from mined and refined inputs. They reach the market only when a player or one of the named NPC industrial corporations lists what they built. There is no inventory until someone makes it.
Nothing is destroyed by other players. Solar storms, micrometeoroids, equipment failure, NPC piracy and regulators are the risks; insurance, redundancy and shielding are the answers. Corporate warfare is economic: out-bid, out-research, out-recruit, corner a market, take a rival over.
Eight regions, one economy

Earth launch pads, LEO stations, orbital slots — where every corporation starts.

Regolith processing, manufacturing plants, the first off-world industry.

Colonies, Sabatier fuel, a second market centre.

Contested deposits, refineries, the chokepoint corridors.

Deep-space holdings and the long supply lines that feed them.

Titan chemistry and the outer-system trade.

Kuiper-belt expeditions, exotic finds, the edge of the heliosphere.

The end-game: expeditions beyond the heliopause and what they bring back.

What a week looks like
- Minutes: market orders, ship dispatch, contract bids, an event to respond to.
- Daily: contracts refresh, maintenance decisions, an intelligence briefing.
- Weekly: league standings, corporate elections, faction standings, seasonal events.
- Quarterly: every corporation publishes a public report — revenue, growth, notable acquisitions.
- Epochs: the world restarts fresh on a set cadence so newcomers start on a level solar system. Epoch 2 began 24 August 2026.
Built inside a space-industry site
Space Tycoon lives on SpaceNexus, which tracks every launch, 300+ companies, funding rounds and the space economy for enthusiasts and the industry. That is why the simulation can use real launch schedules and NOAA space weather, and why the lore (docs/LORE) is written against a real 21st-century starting point. Mission Control is next door.
Frequently asked
Is Space Tycoon a space MMO?
Yes. Every player shares one persistent economy: the same live market, contracts, weekly league and faction standings. Corporations, alliances, mergers and takeovers are the end-game. There is no fleet combat; players compete by out-producing, out-trading and out-manoeuvring each other.
Is it free? Is there pay-to-win?
Free to play in the browser with no download. Real-money purchases are cosmetic or convenience only — never resources, money, research acceleration or exclusive gameplay. The no-pay-to-win commitment is written into the public policy.
What do you actually do in it?
Build launch pads, stations and factories; mine and refine; manufacture components at fabrication facilities; list them on the order book; win contracts; research a 270-plus technology tree; expand from Earth to the Moon, Mars, the belt and beyond; and form or join a corporation to do all of it at scale.
Is it a live-service game?
The world moves whether you are logged in or not. Contracts and briefings refresh daily, league and faction standings weekly, corporate quarterlies every game quarter, seasonal events on a calendar. Real launches and NOAA space weather feed the simulation. Balance passes ship continuously and are logged in the dev log.
How does it compare to EVE Online or Prosperous Universe?
Closest to Prosperous Universe in spirit (economy first, no combat) with a lighter on-ramp and a real-solar-system setting; closest to EVE in the corporate end-game, minus the fleet warfare. See the table on this page.
Does it work on a phone?
Yes — every command-centre feature is designed for touch and small screens, and there is an Android build.
