So, I'mma try for a
historic Troy. Wish me luck! Also, Ryan, did Eli pass on my plans for the thing you wanted help with? =]

Troy (Piyamaradu)
Start Bias: Coastal
Capital:

Wilusiya
UA:
Stormgod Of The Army
Melee Units in your territory may make an additional attack, and gain a +25%

Combat Bonus for the duration of Peace Treaties with Major Civilizations. Ranged Units do additional damage against Fortified Units.
UU:
Ahhiyan (replaces Chariot Archer)
Radically different to the Chariot Archer it replaces, the Ahhiyan is a Melee Unit and has an increased

Melee Combat Strength (10

vs. 6), is substantially faster (5 base movement vs. 4), does not stop in Rough Terrain, and begins with +1 Movement. It also starts with the unique promotion, "Horse-Taming Trojans", which allows it to generate a boost of

Production in all Cities per kill equal to double the

Combat Strength of the unit killed. Upgrades to Knight.
UB:
Harnisaza (replaces Walls)
+7

City Combat Strength, +50 City HP. +1

Production in the City in which it is built for each foreign Unit or Barbarian it kills via Bombardment, rising to +2 during any Peace Treaties.

Tricky to do, but I think I've scraped together a balance between real and Homeric Troy/Wilusa. Slightly irritating, and you might just have to delve into the Troad for a city list, but I think it's an interesting Civ that rewards last-ditch defending, declaring war on everyone at once, and, to quote Theoden, having your enemies "break upon the walls of this fortress like water on rock". It's built entirely around pointing at Shaka, Monty, and everyone else, and saying "Come at me, bro."
Which can
only end well.
