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.

[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 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.
Ehhh….i don’t know what is going on for the ships. I heard ppl recommending cruiser more then the battleship ? And does this shows some kind of broken mechanism on the game ? Btw, they both sucks. Ppl y’all need to get some mods for this game caz the base game ant good man. The novice teaching is ♥♥♥♥, I can’t go more plants at the beginning caz of the freaking empire size, I would like to enjoy a large universal scale empire more then a shrink been at the corner of the cosmos. Luckily mod could have fix that. But seriously, i do think there are some major problems with the game. 30% game content depends on ur brain, imagination is impotent ppl, that’s how we defend our jobs from AI. when my ground assault army was deployed. My brain generated an apocalypse battlefield and it was amazing. I enjoyed destroying xenos plants, purifying the universe. All hail the human race. This game satisfied my 40k dream, as a large scale strategic game. I don’t think there will be a replacement for this but I do hope they could make stellaris2 but the new dlc says otherwise. Don’t get me wrong, I enjoy the new dlc it was quite a fun, but the game is like 10 yrs, it’s like “ die in peace, gramp” I don’t think there will be many new blood Coming in but I hope for the best. May this game thieve for many years, keep updating, keep on the good work and let the players grab the new generation, since the tutorial is ♥♥♥♥, it really depends on YouTube 1 hr videos to get things in mind.
Once a fun game, now a cash-cow made of AI.
content is 300 dollars on top of the base game. Waste of your money to buy the base game.
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
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.
Fun, but its Ubisoft and all the DLC it keeps trying to make you get cost 200+ USD.
i can be evil in space. 10/10
