Medieval Empires is an elaborate, multi-player online strategy game set in what is now modern-day Turkey, during the late 13th century. The storyline of the game initially focuses on Ertuğrul Gazi, a tribal warrior and a celebrated leader of the Kayi tribe. Future faction additions such as the The Holy Roman Empire, Mongols or Byzantines would be added to make gameplay more interesting and to expand the playable world of Medieval Empires.
