Play Sid Meier’s Civilization Online

Sid Meier's Civilization is a turn-based strategy game originally released for MS-DOS in 1991. It was developed by MPS Labs and published by MicroProse Software. The game belongs to the 4X genre, which involves exploring, expanding, exploiting, and exterminating, and is presented from a top-down perspective on a world map.

Players control the leader of a historical civilization, starting with a single settler unit in 4000 BC. The primary objective is to guide this civilization through thousands of years of history, achieving victory through military conquest, technological dominance, or diplomatic means. Gameplay proceeds in alternating turns where the player manages city production, researches new technologies, and moves military and civilian units across a tile-based map. Key systems include founding and developing cities to generate resources, engaging in tactical combat with neighboring civilizations, and navigating a technology tree that unlocks new units and city improvements.

Progression is structured around expanding an empire's territory and influence while interacting with rival computer-controlled civilizations. Players explore the randomly generated world, negotiate treaties, and respond to events such as barbarian invasions. The game continues until one civilization meets a victory condition or a player reaches the modern era and launches a spaceship to Alpha Centauri, marking a scientific win. The experience is defined by long-term strategic planning across multiple interconnected systems of economy, research, and diplomacy.
