Culture/Trade/Defensive in CL? Shome mistake shurely! =]
Anyway, the one I designed ages back was roughly as follows:-
---
Zimbabwe (Changamire Dombo)
Start Bias: Hills/Plains (I can't remember which one it was)
UA:
Chain Across The Highveld
Internal Trade Routes generate
Gold equal to 50% of their
Food or
Production output, rising to 100% after Economics is researched. +5% bonus to
Wonder Production for each National and World Wonder in the
Capital.
UB:
Dzimba Dza Mabwe (replaces Castle)
Standard Castle benefits. +10% additional
City Defensiveness for each Luxury Resource in range of the City in which it is built. Additionally, generates a +2%
Production bonus for each City with a Dzimba Dza Mabwe connected to your Trade Network.
UU:
Amabutho (replaces Lancer)
Gains the Lancer's traits and promotions, but is radically different. It does not count as a Mounted Unit, but rather a standard Melee Unit, and is slower, with a base movement of 3. However, it does not require any Horses and starts with a unique promotion, "Shangani Patrol", grants a percentage
Combat Bonus when attacking a stronger enemy Unit equal to twice the difference in stats. Upgrades to Rifleman.

How the Shangani Patrol works:
Your Amabutho (Strength 25) is attacking a Rifleman (Strength 34). 34-25 = 9, and 9x2 = 18. You get an 18% Combat Bonus.
If your Amabutho is attacking a Knight (strength 20), then you get no bonus. Sorry.
If your Amabutho is attacking a Ranged Unit (say, a Rocket Artillery), then you use the melee strength - 55-25 = 30, 30x2 = 60, and you get a 60% Combat Bonus, which you will need if you are still using bloody Lancers by the time your opponents have Rocket Artillery. =]

So, there's my four-penn'orth. The other unique should be Wonder Production, since CL... kinda doesn't have that yet, not even in the planned Civs in TP's magic book. Oh. Er. Should probably not have mentioned TP's magic book he'll turn me into a fr-
ribbit. ribbit ribbit.
