This thread speculating about upcoming changes to UAs got me thinking: what if you had to overhaul everything? Not just the civs that you expect to see changed, or the ones you'd like to have changed, but every single civ in the game? Change them all so that they have different strengths, favor different playstyles, and are still relatively balanced with one another and diverse. A few militaristic, a few scientific, a few religious, etc.
Having way too much time on my hands (don't tell my boss), I got as far as redesigning all of the vanilla civs using G&K and BNW mechanics, trying to avoid, as much as possible, reusing any ideas from the vanilla game. Credit to ferretbacon, one of whose ideas I tweaked for Japan and another of whose ideas I borrowed wholesale for India.
I've got too many smilies in here (and maybe too much text anyway), so I've got to split it up into four posts.
America
Mother of Exiles: Population
growth and
Great Person generation increased by 30% during a
Golden Age.
Monitor (replaces Ironclad): +5
Strength. Does not require Coal.
Land-Grant College (replaces University): +3
Happiness
Arabia
Houses of Wisdom: During a
Golden Age, all sources of
Faith also produce an equal amount of
Science. Start a
Golden Age upon founding a religion.
Madrasa (replaces Library): +2
faith
Mubarizun (replaces Swordsman): +1
Strength. Enemy units have -10%
Combat Strength when adjacent to this unit.
Aztecs
Triple Alliance:
City-States are more easily threatened, yield greater tribute, and reward quests to demand tribute with greater
influence.
Ball Court (replaces Colosseum): +1
Culture, +1
Faith.
Eagle Warrior (replaces Archer): +3
Strength, +1
Ranged Strength. Earns 50% of opponents' strength as
Faith for kills.
China
Mandate of Heaven: +1
Culture and +1
Science in each City for every 1000 years that
Happiness remains above 0.
Han Cavalry (replaces Horseman): +2
Strength. Starts with Formation I promotion.
Walled Village (improvement): +10% defense for any Unit stationed in this tile. +1
Gold, +1
Production. Cannot be pillaged. Available with Machinery.

Land-Grant College (replaces University): +3

Spoiler :
The idea here is an immigration theme ("mother of exiles" is from the Emma Lazarus poem "The New Colossus," the one about the Statue of Liberty). Pretty simple, but hopefully pretty engagingyou'd not only want to push for Golden Ages, you'd really want to have all your ducks in a row when they came around. The Monitor is sort of boring, but it was the first great American innovation in military science, and I didn't want to have any post-Industrial Era UUs.
Arabia
Houses of Wisdom: During a




Madrasa (replaces Library): +2

Mubarizun (replaces Swordsman): +1


Spoiler :
I think this one is really clever (if I do say so myself). The theme is the Islamic Golden Age; the House of Wisdom was a center of scholarship in Baghdad. Writing comes late enough that Arabia wouldn't be guaranteed an early pantheon, but they should be able to score a religion eventually, especially if they go wide. Techs to boost religion (e.g. Theology), Golden Ages (Civil Service), and the UU all pull the player in different directions, so there's a little tension and it's not all too OP. The Mubarizun were elite soldiers of the first Islamic Caliphate who sought out and killed enemy champions to demoralize and frighten their armies. The promotion would carry over, as with the Maori warrior.
Aztecs
Triple Alliance:


Ball Court (replaces Colosseum): +1


Eagle Warrior (replaces Archer): +3



Spoiler :
All the members of the real Triple Alliance are just Aztec cities in the game, I think, but I liked the idea of a UA that would encourage the player to befriend some city-states and bully others (I know in my games I rarely, if ever, carry out quests to demand tribute). Subject to tweaks for balance, I was thinking that tribute would be twice as large (maybe two workers is OP, though) and successful quests to demand tribute would yield 50-100% more influence. Eagle Warriors fought with atlatls, bows, javelins, etc. so I figured they could be a ranged unit; they take captives and sacrifice them to the gods. Between the UA and the UB, these Aztecs have a minor religious flavornot necessarily going to found an early pantheon or establish a dominant religion, but they have a little edge if they work at it.
China
Mandate of Heaven: +1



Han Cavalry (replaces Horseman): +2

Walled Village (improvement): +10% defense for any Unit stationed in this tile. +1


Spoiler :
This UA would probably be really hard to balance, but I like the concept: so long as the empire remains stable and the people are happy, China gets more and more glorious. Because the bonus is year-based, not turn-based, there's an incentive for a Chinese player to expand as much as possible as quickly as possible and then go tall; it would also discourage China from embarking on major wars of conquest (all of which seems historically sound to me). The UU lets China chase Huns and Mongols from the borders of their early empire, as in history (well, maybe not Huns); the UI is just a little flavor and a slight perk, since it comes before Chemistry and Economics. I think these structures would look super cool all over Chinese territory (although maybe a terrain limitation is in orderjust hills and coasts? just grasslands?).
