Following the Cree announcement last week—and the criticism that followed—2K and Firaxis have unveiled the next civ en route to Civilization 6. Led by Golden Age ruler Tamar, Georgia will feature in the geopolitical strategy game's incoming Rise and Fall expansion. 

As detailed in the 'First Look' trailer below, Georgia's unique ability is Strength in Unity whereby the player receives an additional bonus when transitioning into a Golden Age. Naturally, this means Georgia is better placed to achieve and, crucially, maintain Golden Ages over rival civs.
