Galactic Civilizations IV is a 4X space strategy game set in the 24th century. Humanity has achieved faster-than-light travel and is now competing with alien civilizations for control of the galaxy. Start with your home planet, research new technologies, explore, colonize, and manage the happiness of your population at home while engaging in trade, diplomacy, espionage, and war abroad. The fourth installment adds leadership appointments, sector exploration, a redesigned combat and invasion system, deeper research options, story-driven missions, and a four-axis ideology system that shapes how your civilization develops and how others perceive it. The galaxy is waiting to find out how you rule.
