Playing it together
Long empire-building games with friends, but online play is rough and buggy.

- Split roles like navy, politics and colonies between players
Cons
- Multiplayer has bugs and poor performance that stayed unfixed for years
- Mandatory expansions make the full game with friends very expensive

About Stellaris
Stellaris is a real-time 4X grand strategy game set in a procedurally generated galaxy. Players control an interstellar civilization, exploring star systems connected by hyperlane networks, colonizing habitable worlds, and managing their empire's economy across resources like energy, minerals, and alloys. The game emphasizes empire customization through species traits, ethics, government types, and civics that shape both aesthetics and mechanics. Gameplay progresses through diplomacy, trade, and warfare with other civilizations, while mid-game and late-game galactic crises introduce escalating threats such as extragalactic invasions or hostile artificial intelligence awakenings. Players can pursue ascension paths including genetic engineering, cybernetic augmentation, or psionic abilities. Originally released for PC, the game later received a console edition and has been supported with numerous expansions adding megastructures, new empire types, espionage mechanics, and additional crisis scenarios.
