i really can't see who would of risen up to replace rome, it would of taken the other civ's at the time to change their way of life so much we can't predict who would become what in time. the carathagians were interested only in a trading empire, their later agressive behavoir was due to rome itself. the greeks were hopelessly divided and even forming city-state leagues wouldn't get you the world. the persia was a large but revolt plagued empire that could barely hang on to itself, not conquer even larger lands. the etuscans, samites and othert italians were not very agressive compared to rome, i doubt one would rise to the top, the mts in italy divided them into 10-12 pockets where they were content to live till rome approuched. the celts and germans were just raiders who loved to fight each other or anyone. it would taken a major change in character in one of these cultures to push it down romes path. rome was special for its time and thats why she and not others rose
