Microsoft's Larry Hryb ("Major Nelson") has responded to the rumors that Xbox-based games were coming to iOS and Android. It's just Age of Empires.
"Some reports included incorrect information about additional Xbox based games on iOS and Android, but there are no further announcements beyond Age of Empires at this time," Hryb wrote on his blog.
KLab America announced that it's developing a mobile version of Microsoft Studio's Age of Empires historical real-time strategy game franchise. KLab's fantasy-card-battle game Lord of the Dragons has gone global and reached the top-10-grossing charts in Japan and the U.S. back in March.
