According to a report from Polygon, Microsoft are going to bring Age of Empires to mobile devices. The game will be free-to-play, meaning it will likely be either a port, or similar to, Age of Empires Online.
Here is the statement from Microsoft:
“Today, KLab Inc. announced a licensing agreement with Microsoft Corp. to develop a mobile version of Microsoft Studio’s Age of Empires franchise, which will be initially developed in English for iOS and Android and launched globally, with plans to release the game in other languages and on Windows Phone in the future. Some reports included incorrect information about additional Xbox Live-based games on iOS and Android but there are no further announcements beyond Age of Empires at this time.”
The game is due for release before the end of the year. Unfortunately, there is no news as to whether a new game in the series will come to PC.
