The game from Zynga is set to launch Wednesday. It is like a mix of the classic strategy game "Risk" and "CityVille," where players oversee virtual cities. Unlike the company's other games, which give points for helping neighbors, "Empires" lets Facebook users play against one another.
The new game comes amid growing chatter of an initial public offering for San Francisco-based Zynga. The company is not commenting and has not yet filed any IPO papers.
