Age of Conquest III

Age of Conquest is a medieval Risk-like turn-based strategy game. As additions to the classic Risk, Age of Conquest features diplomacy, building options and basic economy management. 

All the players can enter their orders simultaneously at the same time (in contrast to Risk), i.e. a player doesn't have to wait for others to finish their turns. 

This makes it possible to have over 100 players in the same game without ever having to wait for others. Age of Conquest supports single player and cross-platform multiplayer games with 100 and more players per game.
