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.

FIX THE BUGS!!!!!!!!! Don't buy DLC!!! The half of them is broken!!!!
i dont recommend this game anymore,this game used to be way better than now but paradox finds a way to ruin the game every second update, first like every other pdx game it has to have 30dlc's of wich most are just mods locked behind a paywall,some mods like gigastructural engeniering or dark space add more features/origins or megastructures than most of pdx dlc's, second the performance of this game is absolutly horrible,if you dont turn of any empires and only allow pre ftl civilizations at game start you bascicly cant play this game past the early/mid game,and how is the performance so bad if the ai builds like no fleets and have those horrible managed planets?pdx should make it so that ai planets have a base ammount of resource production so that the game has to do less calculations,but that whould take development time from developing the 20th slop dlc with 3new origins and 5new civics,and the 4.3 update was supossed to "improve" performance by reducing ship counts,in reality it just made the game less realistic and the performance with many ai empires is still terrible,that had the negative side effect of making average to below average players struggeling even more with endgame criseses and fallen/awakened empires, third,they break the game in every third update,for example in the last update they had to change the megastructure building ui for no reason,that broke multiple megastructures in gigastructural engeniering and it also it broke the display of the output of megastructures and they also reworked the automation ui for science and construction ships wich also broke ui overhaul dynamic a mod that should be part of the base game. in conclusion i dont recomend buying the game if you dont have a nasa supercomputer or have too much money,also dont buy the dlc subscription,just pirate the dlc's to test them out and if you like them you can buy them but i whoulnt give this terrible companie that releases early acces games at launch and only makes them good after 15dlc's and or patches,they dont need the money,they have enough and use it for the absolutly wrongs thing.
Once a fun game, now a cash-cow made of AI.
I don't like how they removed a bunch of interesting things after the game launched, like everyone starting with different FTL methods.
3.9の頃が一番楽しかった。
Honestly just don't bother, 100x easier to at most buy the base game on a heavy sale, than pirate it to get all the DLCs. You're not even going to miss out on workshop mods since they still work normally.
fix your damned game and stop changing everything every time you release a new dlc. this is what the 12th rework on planet management since launch. just fix the game, why do desyncs cause the AI to go brain dead after we do the resync? why does the button to make sectors not work at all? why did my main station just magicaly get teleported away to a system i dont even control after doing the fighting tournament? FIX YOUR DAMNED ♥♥♥♥ and STOP MESSING WITH IT!
[h1]232 hours in and it still humbles me[/h1] 232 hours in and this game still humbles me, which is exactly why I keep booting it up. Stellaris nails the thing that makes a 4X actually addictive. You get to watch your civilization's story play out as you unlock new tech and catch dynamic threats and opportunities you didn't see coming. The [b]origin system[/b] and the [b]tech tree[/b] do a grip of the heavy lifting. No two starts feel the same, and the tree branches enough that you're always building toward [i]your[/i] version of an empire instead of some scripted one. Real talk though, the best part isn't even winning. [spoiler]One run I built up what felt like unstoppable galactic power, hit a wall in a stalemate, then got smacked with an end-game crisis invasion that turned into a war of attrition I had zero logistics to deal with. I rage quit. Not because I was mad at the game, but because I genuinely thought I had it figured out and got played instantly. That moment is the whole reason I love this thing. It doesn't let you coast.[/spoiler] [b]Heads up though.[/b] The vanilla UI is kinda bogus, and if you're not already a grand strategy head, the learning curve is no joke. Give yourself time to actually sit down and learn the systems before you expect to have any fun. If you've messed with Cities: Skylines, Civ V or VI, or even Microsoft Flight Simulator, this is what happens when you take a builder/sim and bolt on politics, governance, and war, all wrapped in sci-fi that's grounded in real theoretical science instead of straight fantasy. It's less about winning and more about living through a whole civilization's rise, its mistakes, and its reckonings. And somehow that ends up way more addictive than winning ever would be. [hr][/hr] [b]Recommended[/b], especially if you like your strategy with a story attached.
i genuinely love playing this game but the AI usage has killed it for me. all that money from the DLC's just for genAI? greedy
I dont know why all give this game i positive review yes this game could be ez a 9/10 or even a 10/10 but bugs bugs and more bugs. The worst it is when an other ki declares war on the same ki that you already are in war in then it ♥♥♥♥♥ everthing up almost every time. So if you like to conquering then you wont have 1 bug free game i promiss you that. It didnt happen in 170 h playtime for me. If i wana make a list of bugs here i need to write a book. And apparently my PC is to weak to calculate how mutch resource 500k pops produce.
