Before you purchase this game, keep in mind that it is quite old, and the graphics are not up to date.
Battle of Empires, or BoE, is a very fun and entertaining game that you can play for hundreds of hours on single player alone. It is pretty much Men of War but focused on the first world war instead of the second. Many different vehicles, guns, emplacements and missions. Only down side being the paywall behind most of the missions. Other than that, it is a very solid game that deserves to be more well known than it's current state.
