Rules-wise, if you've played Commands & Colors: Ancients, you'll have no trouble at all learning the few special rules for these legionary infantry units, for the basic mechanics remain unchanged. The battle dice resolve combat quickly and the Command cards provide an element of luck that creates a fog of war and presents players with both challenges and opportunities for victory. Yet the tactics you need to execute conform remarkably well to the advantages and limitations inherent to the various Ancient units, their weapons, terrain and the history.
But that's not all... GMT is also going to include another mounted mapboard in Expansion #3, configured to be mated to the mounted board from Commands & Colors: Ancients Expansion Pack #2: Rome and the Barbarians. In addition the Commands & Colors: Epic Ancients new Command rules for fighting large-scale historical battles will provide those of you interested in fighting truly large-scale, multi-player, ancient battles the perfect and unique opportunity to do so with a number of your friends.
