The strategy title's due for release at the end of June.
Microsoft has announced that it will bring strategy title Age of Empires to iOS and Android by the end of the fiscal year, which in non-accounting speak means end of June 2013. The original Reuters report cited unnamed "other titles" to follow the Age of Empires launch, but Microsoft has since said, in a press release, that "there are no further announcements beyond Age of Empires at this time."
Age of Empires is being adapted for mobile by KLab Inc., a Japanese smartphone game maker. Age of Empires, for those unfamiliar with the title, was one of the first history-based RTS titles, when it launched back in 1997 as an Ensemble Studios product. You guide your civilization from a scrappy little nothing to a full-fledged empire, building up an army and collecting resources until you are a power to be feared. The mobile version will be a free-to-play title.
Though Microsoft's determined to keep all its cats in the bag, it seems reasonable that - if Age of Empires is a success - other titles might make the jump to a mobile platform, at some point in the future. Just not right now.
