Development of the game was announced on 15 February 2010 via press release, then put on hold indefinitely in 2013, and ultimately was cancelled when the company was closed in 2018.

[citation needed] Although specific gameplay details are few, the game represented a departure from Gas Powered Games prior RTS series, Supreme Commander, given a new setting in a fantasy universe.

[2] This was similar to the transition made by Total Annihilation: Kingdoms after the original Total Annihilation (both running on the same engine, the latter designed by Chris Taylor).

[3] The game was extensively marketed in 2010 via a variety of social media channels, including an official video blog, company Facebook page, game Facebook page, and official Twitter account (@GasPoweredGames).

However, even after the completion and release of Age of Empires Online, it was still on hold indefinitely until the game was cancelled when the company was shuttered in July 2018.
