Were you planning your gaming calendar around Age of Empires: Definitive Edition's release on October 19th? You'll... need to find an alternative. Microsoft has pushed back the launch of the remastered real-time strategy collection at the last minute, anticipating a launch sometime in early 2018. The developers pin the sudden delay to a desire to tweak the game as much as possible. They want to invite "thousands" more people into the closed beta to adjust everything from the multiplayer balance to the lobby system.
