Week in Space Data, every Friday.
“Space game” usually means flying. This is the shorter list of games where the market is the game, where what you build, mine, make and sell matters more than what you shoot. One of them is ours; it is listed last and we say so.
| Game | Platform | Price | Combat | Multiplayer economy |
|---|---|---|---|---|
| EVE Online | PC / Mac client | Free-to-play tier; subscription for full skills | Central. The economy exists to feed wars. | Yes: shared with other players |
| Prosperous Universe | Browser | Free tier; subscription for more bases | None. | Yes: shared with other players |
| X4: Foundations | PC | Paid + expansions | Yes, and you can fly every ship. | Simulated, single player |
| Elite Dangerous | PC / console | Paid | Yes. | Simulated, single player |
| Starsector | PC | Paid (in development) | Yes, tactical fleet battles. | Simulated, single player |
| Space Tycoonours | Browser (installable web app; Android app listing pending) | Free; cosmetic purchases only, no pay-to-win by policy | None: rivalry is economic. | Yes: shared with other players |
The economy: The deepest player-run market in gaming: regional hubs, manufacturing from blueprints, planetary industry, freight, speculation. Prices are entirely player-set and CCP publishes monthly economic reports.
Combat: Central. The economy exists to feed wars.
Best for: People who want a real economy and are willing to lose ships in it.
The catch: Two decades of accumulated wealth and knowledge; new players enter an old economy. Losing what you build is the point.
The economy: A production-chain simulation with commodity exchanges, contracts and shipping between player bases. Everything is made by someone; spreadsheets are encouraged.
Combat: None.
Best for: The player who wants the EVE market without the EVE combat.
The catch: Slow by design, decisions play out over days, and the interface is a spreadsheet with a space theme.
The economy: A fully simulated single-player universe: factions build stations, ships haul wares, prices respond. You can own the whole supply chain.
Combat: Yes, and you can fly every ship.
Best for: Solo empire-builders who want to watch an economy they seeded run itself.
The catch: Single player: the economy is simulated, not contested by other people.
The economy: Trading, mining and missions on top of a background simulation of a 1:1 Milky Way; commodity prices drift with system states.
Combat: Yes.
Best for: Pilots who like the trade loop as a break from the flying.
The catch: The economy is a backdrop, not a competition: you rarely out-trade another person.
The economy: Colonies, industries, market share and a smuggling economy in a single-player sector; famously moddable.
Combat: Yes, tactical fleet battles.
Best for: Players who want colony economics with a real fleet game attached.
The catch: Single player; economic play is a layer over combat.
The economy: One shared live market for every commodity and service; manufacturing at fabrication facilities; hardware listed by players and named NPC industrial corporations; contracts, corporations, alliances, takeovers; real launches and space weather feed the simulation.
Combat: None: rivalry is economic.
Best for: People who want a multiplayer space economy in a browser tab without the combat or the subscription.
The catch: Young. The player base is small and the world restarts on an epoch cadence (Epoch 2 began August 2026), which is a feature for newcomers and a trade-off for veterans.
For depth and scale, EVE Online: a two-decade player-run market that CCP reports on like a central bank. For an economy without combat, Prosperous Universe and Space Tycoon are the two multiplayer options; X4 is the best single-player simulation.
Yes: Prosperous Universe (browser, subscription for scale) and Space Tycoon (browser, free, no pay-to-win) are both multiplayer economies where players cannot attack each other; risk comes from markets, hazards and NPC factions instead.
EVE has a free-to-play tier with skill limits; Prosperous Universe has a free tier limited in bases; Space Tycoon is free with cosmetic-only purchases. X4, Elite Dangerous and Starsector are paid.
Prosperous Universe and Space Tycoon. The rest need a client.
