Compare X3: Reunion prices across trusted key stores and find the best deal. Developed by Egosoft. Published by Egosoft. Released on 7/21/2006. Available on PC. Genres: Strategy. Metacritic score: 71/100.

A deep space sandbox from 2006 that lets you trade, fight, and build a corporate empire across a living galaxy - if you can survive the learning cliff.

X3: Reunion is a space sim and trading sandbox developed by Egosoft, sitting somewhere between a grand-strategy economy game and a full-blown space combat sim. You start small - one ship, limited credits, a galaxy that does not care about you - and you grind your way up through trading routes, piracy, factory construction, and eventually running a multi-sector industrial empire. The universe runs its own economy whether you interact with it or not, with AI factions buying, selling, and fighting in real time. That living economy is the core hook, and it still impresses even measured against modern competitors. The depth here is genuine and punishing. You can manually fly combat missions, but the real game opens up once you start scripting automated freighters, building production chains, and optimizing sector coverage with a fleet of AI-controlled ships. The build variety is enormous: trade configurations, combat loadouts, factory complexes, and sector defense grids all demand planning. The late game, where you are managing dozens of ships and a sprawling economy, is where X3 justifies every hour of friction you endure to get there. That friction is real, though. The tutorial is thin for a game this complex, the UI is a product of its era, and some mechanics are explained better by fan wikis than by the game itself. For newcomers considering this in the current year, the honest pitch is this: X3: Reunion is a 2006 game with 2006 interface conventions, but the underlying simulation has more moving parts than most modern space games bother to model. If you are patient enough to read community guides and accept that your first run will be a learning run, the payoff is a sandbox that rewards systems thinking in a way that few games do. The mod ecosystem on the Steam Workshop and third-party sites extends the game significantly, adding quality-of-life fixes that make the experience noticeably more approachable. Install the community patches before you do anything else. What does not hold up: the story missions are mediocre, the voice acting is rough, and the graphics are dated even by the standards of the mid-2000s space sim genre. Combat is functional but not exciting - you are not here for dogfighting thrills. The mixed Steam review score reflects a real divide between players who bounced off the steep entry curve and players who sank 500 hours into sector logistics. Both reactions are legitimate. The AI in combat scenarios is serviceable but not clever, and enemy fleets mostly serve as economic hazards rather than strategic threats you have to outthink. If you have already finished X4: Foundations or Elite Dangerous and want to trace the lineage of the genre, X3: Reunion is a fascinating historical artifact that still functions as a playable game. If you want a modern entry point to the X series, X4 is the better purchase. But if the idea of a fully simulated galactic economy with deep production chains and 200-plus hours of emergent gameplay sounds compelling, and you are willing to treat the first ten hours as tuition, X3: Reunion delivers something genuinely rare.

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
