Age of Mythology is a real-time strategy video game developed by Ensemble Studios and published by Microsoft Game Studios. It was released on October 30, 2002 in North America and a week later in Europe. A spin-off from the Age of Empires series, Age of Mythology takes some of its inspiration from mythology and legends of the Greeks, Egyptians, and Norse, rather than from actual historical events. Many gameplay elements are similar to the Age of Empires series. Its campaign follows an Atlantean admiral, Arkantos, who is forced to travel through the lands of the game’s three cultures, hunting for a cyclops who is in league with Poseidon against Atlantis. Age of Mythology was commercially successful, going platinum four months after its release after selling over one million units. In 2003, it was followed by an expansion pack, Age of Mythology: The Titans. On May 8, 2014, Age of Mythology: Extended Edition was released for Windows via Steam. This was followed by a second expansion pack, Age of Mythology: Tale of the Dragon, released on January 28, 2016.
