What kind of game is Factorio?

Factorio is primarily a construction and management simulation focused on building automated factories: you mine resources, research technologies, design logistic networks and automate production chains while defending your base from alien creatures. The game blends automation-focused simulation with real-time strategy and survival elements, and offers both single-player and cooperative multiplayer modes — the official site and store describe it as a game about creating automated factories and protecting them.

Under the surface the gameplay centers on a few clear pillars: resource gathering, conveyor/logistics systems, manufacturing (assemblers, furnaces), power and fluid management (including oil refining), research trees, and combat. Typical player goals range from small handcrafted setups to massive, highly optimized production complexes and optional end goals such as launching a rocket. Factorio also supports extensive modding and a built-in map editor, letting communities create scenarios and large-scale cooperative factories.
