Stellaris

Stellaris is a grand strategy space 4X game where you guide a custom-built civilization to explore a living galaxy, expand your empire, and shape its destiny through diplomacy, discovery, and war. It features deep empire building with ethics, civics, and species traits, dynamic narratives from anomalies, events, and galaxy-spanning crises, and layered strategy from research and megastructures to espionage, federations, and titanic fleet battles. Every campaign evolves differently as you chart the unknown, negotiate with alien powers, and decide whether to cooperate, dominate, or ascend.
