Shadowmere

"The object of this multiplayer, online strategy game is to try to become the most powerful player through warfare, magic, diplomacy, or covert attacks. No single strategy will work for every race. For example, Dark Elves are extremely talented at covert operations, are moderate fighters, and are magic users whereas Ogres can smash the smaller races through brute force. "
