The game is much the same as the original Rome: Total War, but with fewer factions, different units, and a different map. It begins with Alexander's ascension to the Macedonian throne in 336 BC and lasts for 100 turns. It is set in an earlier time period, putting the player in the role of Alexander the Great. Rome: Total War: Alexander is the second expansion pack for Rome: Total War.
