Here's my comments on Georgia's Uniques/Abilities:
Civ Ability-Strength in Unity: When changing eras into a golden age, you receive an additional bonus on top of your golden age bonus.
Not very interesting as others have mentioned. It reminds me of the Byzantine ability in Civ5. The name refers to the official motto of Georgia,
Dzala ertobashia. It reminds to be seen how powerful the additional Golden Age bonuses are.
Leader Ability-Glory of the World, Kingdom and Faith: +100% Faith for 10 turns after declaring a Protectorate War. Each envoy you send to a City-State of your majority religion counts as two envoys (must have a majority religion).
“Queen of Kings and Queens, Glory of the World, Kingdom and Faith, Champion of the Messiah, may God Increase her victories.” - Inscription on 13th-century Georgian coins
I'm not surprised to see her ability involving faith. I'm not familiar enough with Medieval Georgian history to know if Tamar fought wars to protect her allies, but she probably did. The two envoys is similar to
Diplomatic League, but with a limitation, Georgia and the City-State must share the same religion.
Unique Unit-Khevsureti: melee unit, gains a combat bonus on hill terrain, ignores all hill movement penalties.
As a poster pointed out, the name refers to a
region. No unique Georgian hand ring weapons? A shame....The hill bonuses are nice to have. I wonder if it's a Medieval era unit.
Unique Building-Tsikhe: a replacement for Renaissance Walls, built at a lower production cost and provides faith, also tourism with the Conservation Civic.
Tsikhe means "fortress" in Georgian. These Georgian fortresses are not usually protecting cities/settlements though based on what little I know. Most players don't bother to build Renaissance Walls....
Conclusion: Many Civfanatics are underwhelmed or disappointed by Georgia's uniques and abilities. Some even say this is a reason why the Civ shouldn't have been included in the first place.
But it's the game designers' fault for choosing these abilities/uniques in the first place, not the fault of the Georgian people/history/civilization. I'll play them at least once when I finally buy the expansion.
