This maps are result of a simply copy and paste. The maps Italy and Bizantium from Ensemble Studios really "ensemble"!
Two maps are included in the zip file, a blank map for scenario designers (Balcanes4), and a "filled" map ready to playing (BalcanesRM2). This one are a multiplayer map, featurin Roma, Venecia, Sicilia, Croatia, Serbia, Greece, Albany, and the temible Bulgarians (huns).
And for the names of the maps, is because the numeration of saving in the editing (or copy-pasting...).
