The game was originally planned for a release in 2017, but unfortunately the game has since been delayed to “early 2018”. No specific dates have been mentioned but according to the game’s developer, “When we set out to re-release the original Age of Empires (as ‘Age of Empires: Definitive Edition’), we had many debates over the extent of restoration that we should undertake. The challenge of re-releasing a classic is just that: it’s a classic and it deserves to be treated with careful reverence.”
“To that end, rather than a final release of Age of Empires: Definitive Edition on October 19, we will instead be inviting thousands more players from the community into our closed beta between now and launch to allow for more in-depth testing across single player campaign, multiplayer balance, fine-tuning the lobby, etc.”
We suppose there are probably some who might be disappointed by this piece of news, but unfortunately it appears that there’s really nothing we can do but wait. In the meantime Age of Empires IV has also been announced but details and a release date for the game is also unknown.
