Sid Meier's Civilization V/Persia

There were many empires that sprung up around the Persian region, but the one in this game specifically represents the Achaemenid Empire. It is led by Darius I, a satrap turned king who expanded Persian borders and improved his empire's organization and infrastructure. Persia has one of the best Unique Abilities in the game, with a major focus on getting and taking advantage of long Golden Ages. With an incredibly resilient early-game unique unit and a unique building that synergizes with their Unique Ability, Persia can take on any victory condition and still keep up with the competition.
