About
Get ready to explore, discover and interact with a multitude of species as you journey among the stars. Forge a galactic empire by sending out science ships to survey and explore, while construction ships build stations around newly discovered planets. Discover buried treasures and galactic wonders as you spin a direction for your society, creating limitations and evolutions for your explorers. Alliances will form and wars will be declared.
Like all our Grand Strategy games, the adventure evolves with time. Because free updates are a part of any active Paradox game, you can continue to grow and expand your empire with new technologies and capabilities. What will you find beyond the stars? Only you can answer that.
Stellaris now includes the base game, three expansion packs, and a collection of digital goods.
Stellaris: Chart a vast, procedurally generated galaxy where every star system holds a new mystery to uncover or an alien civilization to encounter. Forge a unique empire: from your first warp jump to galactic domination, you decide whether the universe remembers you as a benevolent pioneer or a relentless conqueror.
Utopia: Unlock the full potential of your empire with this expansion focused on the evolution of society. Whether you're building mega-structures or ascending to a higher plane of existence, Utopia helps you create a future that’s as bright as the stars themselves.
Synthetic Dawn Story Pack: Take command of a Machine Empire and reshape the galaxy in your own image. Will you lead your mechanical creations to peaceful coexistence, or will the rise of synthetic life spell the end for organics?
Humanoids Species Pack: the most-played phenotype now gains more variety with unique civics and a new origin. Along with their own unique ship class, new portraits, and more, there’s never been a better time to explore the future of humanity.
And on top of this, the Digital Collector’s Book, a Signed Wallpaper, a Unique Forum Avatar and Icon!
Every game begins with a civilization that has just discovered the means to travel between stars and is ready to explore the galaxy. Have your science ships survey and explore anomalies, leading you into a myriad of quests, introducing strange worlds with even stranger stories and discoveries that may completely change your outcome.
With characteristically complex unique planets and celestial bodies, you will enter a whirlwind of spectacles in a highly detailed universe.
Through customization and procedural generation, you will encounter infinitely varied races. Choose positive or negative traits, specific ideologies, limitations, evolutions or anything you can imagine. Interact with others through the advanced diplomacy system. Diplomacy is key in a proper grand strategy adventure. Adjust your strategy to your situation through negotiation and skill.
An eternal cycle of war, diplomacy, suspicions and alliances await you. Defend or attack with fully customizable war fleets, where adaptation is the key to victory. Choose from an array of complex technologies when designing and customizing your ships with the complex ship designer. You have a multitude of capabilities to choose from to meet the unknown quests that await.
Grow and expand your empire with thousands of randomly generated planet types, galaxies, quests and monsters lurking in space.
Customize your Empire! The characters you choose, be it a murderous mushroom society or an engineering reptile race, can be customized with traits like ethics, type of technology, form of preferred space travel, type of habitat, philosophies and more. The direction of the game is based on your choices.

mixed feelings: game feels broken. Design flaws. Bad AI. Some of the greated addons are in the workshop while the paid DLC often don't add anything interesting. I would give it a 6.5/10, but it is vastly overrated on steam, so a thumbs down.
They released a DLC that added so many bugs it made the entire game unplayable rage bait WITH THE DLC DISABLED. Probably used AI code or some ♥♥♥♥♥♥♥♥ with no play testing.
ANOMALY DETECTED: The Paradox Loop Science Officer Xirmian reports a disturbing discovery on the lifeless tomb world of P-3X. Buried beneath layers of oxidized silicon, the crew of the ISS Sunk Cost Fallacy has unearthed a functional, two-dimensional temporal window running a staggering, universe-spanning simulation designated "STELLARIS (Build v4.4)." Our researchers are baffled by the simulation's operational parameters. It appears to simulate an entire galaxy, commanded by an omnipotent, unseen entity whose primary objective is extreme micro-management. According to the data logs, this entity will spend standard centuries meticulously editing the genetic code of aquatic space geckos, only to immediately enslave them upon discovering a slightly more efficient species of lithoid rock-people. The anomaly exhibits several highly concerning paradoxes: The Temporal Slowdown: As the simulated galaxy becomes more populated, the very fabric of space-time decays into an agonizing crawl. The logs indicate the omnipotent entity routinely solves this "lag" by constructing a colossal superweapon and shattering heavily populated worlds — not out of malice or strategic necessity, but simply to reduce the simulation's processing load. Our scientists have dubbed this phenomenon "Genocide by Framerate." The Tribute Cycle: To experience new dimensions of reality within the simulation — such as constructing a Dyson Sphere, participating in galactic espionage, or experiencing a machine uprising — the entity is forced to periodically sacrifice localized currency to an extra-dimensional collective known only as "The Developers." The Abandonment Protocol: Curiously, almost none of these simulated universes ever reach their natural conclusion. Right around the simulated year 2350, when the endgame crisis approaches and the micromanagement becomes unbearable, the god-entity abruptly abandons the universe out of sheer boredom. It then instantly sparks a brand new Big Bang just to try a "Tall Mega-Corp" build. Xirmian notes that the simulation is highly addictive, despite consisting mostly of staring at colored spreadsheets, managing unemployed clerks on newly conquered habitats, and completely ignoring the mandates of the Galactic Community.
This game has for a long time been my go to strategy game, but with the most recent dlc Nomads adding AI generated voices as well as costing $25 I just can't convince myself to recommend it to people. It is a fun game, but the dlc pricing and increased AI use dampens the fun dramatically. I don't want to support a company that is heading that direction.
Игра прекрасна, подход разработчиков и маркетинговой компании ужасен. Новые игроки не могут теперь купить все дополнения по старым ценам, ведь их подняли почти в 2 раза и добавили подписку... не говоря про то что многие дополнения выглядят как вырезанный контент из основной игры. Я не против подписки, пусть будет, для многих это выгоднее, для "мимо проходящих", но что если я полюбил игру так, что хочу скупить все дополнения и не думать о подписке? Теперь это стало дорого и я посматриваю на подписку чаще, если захочу начать новую игру. Не уж-то этот мир победил маркетинг и пропаганда?
I do NOT like the changes to fleets and economy management Used to be big space battles towards the endgame that made getting there worth it, now it's like half that and feels like a chore to get through just to fight the crisis. And managing planets was easy. You settle, you build it up, and a couple decades later it becomes productive. Simple as. Now I have no workers anywhere unless I use slaves or otherwise micromanage the population of every planet so that the worker population can catch up with specialists. It's exhausting and I hate it. I don't care if this increased performance, and no, this didn't add "personality" to every planet. It just made them all likewise frustrating at their lack of productivity and the constant need to micromanage the population. Planets probably had more personality back when things were simple. Paradox, I beg you, add a classic settings toggle
убил хтоническую термоядерную сущность кучей голодных амёб, отрезал ей яйца и выставил в столице. 10/10
Gutes Spiel aber zu häufige Änderungen ohne, dass hierauf groß Einfluss genommen werden kann. Für Gelegenheitsspieler besteht kaum eine Möglichkeit eine Partie zu beenden ohne, dass ein Update die Savegames zerschießt. Ich fange nicht erneut an. War jetzt meine letzte Partie für einige Zeit.
♥♥♥♥♥♥ ска лейтгейм. старый уёбский движок для одноядерных процессоров превращает игру в забег на скорость пока процессор не перестанет обрабатывать каждый тик по секунде. а эти ♥♥♥♥♥♥♥♥ парадоксы длс клипают да фичи на клаузвиц накидывают с костылями. самое обидное игра то пиздатая, е из-за движка нулевых ♥♥♥♥♥ доиграть не можешь, максимум просто уменьши галактику до 5 звёзд и летай там как ебланг
The new nomad features are entirely broken. Not only are they chronically underpowerd and unable to properly defend themself, the sheild debug on their mothership is dumb, the influence cost for everything is chronic and makes them horrifically unscalable, and the new automation mechanics, whilst better than the old dynamics are broken and sent me directly into the enemy. Just dumb, fix it, and test stuff before release, it's not hard!!!
