Ensemble Studios was an American video game developer. It was founded by Tony Goodman in 1994 and incorporated the following year. It borrowed the name of Ensemble Corporation, a consulting firm founded by Goodman in 1990.[1] It was acquired by Microsoft in 2001 and operated as an internal studio until 2009, when its development capabilities were officially disbanded.[2] Ensemble developed many real-time strategy games, including the Age of Empires game series, Age of Mythology, and Halo Wars. In addition to game development, Ensemble Studios also made the Genie Game Engine used in Age of Empires, Age of Empires II: The Age of Kings, and Star Wars: Galactic Battlegrounds. The studio sold 20 million games and was worth an estimated $500 million.[3]
