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.

Now, this game is one of the breeding grounds for cool writing ideas. If you ever thought:"Hm, I wonder how I should write xyz sci fi story" or "How should I world build my sci fi world?" Playing this game with mods included gives you quite a big range of ideas, some with more cosmic horror than others. How good is the game itself? Well, with all the dlc's out by now, they are a must for all of the additional content they add (although some are way more worth it than the others eventhough the prices are not necessarily justified unless they're 50% off). A problem so far seems to be Paradox's lackluster DLC content compared to before. One thing I think the community would agree on would be: Give us more (and different) Crisis both mid and engame, since its one of the climaxes that the game leads towards. Paradox also seems to struggle to balance the Tall Empire playstyle (little territory, lots of income and output) vs the Wide Empire playstyle (lots of territory and moderate income and output) aswell as...the multiplayer experience. With the multiplayer experience, you host better have a NASA PC because otherwise, you will get more desync's than you'd like but this is a paradox issue across most of their games which in turn should be a top priority issue to deal with, but I'm pretty sure they'd rather keep that to a minimum to release more dlc's since that seems to be their earning strategy. Conclusion: If you want to play this game with a budget PC, you should know that your multiplayer sessions may be torture once you hit mid-game. If want some dlc's, take those at at least 50% off, especially the newer ones since they add less content than most older ones. About the mods: Modding the game expands the games content or even fixes balancing issues but some mods may take a while to be updated after the release of a new version because it seem to be similarly painful as Helldivers 2 for modders to keep things updated or fixing their mods. Extra recommendation: Don't shy away from reading through the random events of the game especially if you're a writer or (book) reader. You get fairly interested into the games lore or even the lore that modders ad with their mods. I've come across some quite creative works throughout my countless playthroughs.

Serious Review: They killed my amoeba whale child 4000 hours ago and I've been speed running from barely functioning space society to full Fallen Empire hunter just to steamroll them. Everything I build has a tagline of "Bubbles" so I don't forget my goal. Sometimes I let the Fallen Empires awaken just so I can put them back to sleep so they understand their dreams were the only safe place for them. I will never forgive, and I will never forget. Other review: Very solid 4X game I don't necessarily think you need ALL the DLC to enjoy it, but if you do want it wait for a sale and scoop them. You shouldn't be paying an annual fee to enjoy this game, and I think the prices are to try and push people into getting the subscription. All in all if you like 4X games I'd say to most people this won't be lower then a 7/10 in their eyes. Just get the DLC's you want on sale and you'll have a great time
