Here's one I've been working on for a bit.
Aurangzeb - The Mughals
Agra (not sure what his backup capital should be atm)
UA: World-Seizer
Inquisitors and Great Prophets may be used to remove rival religions from your cities up to three times. Whenever a city following an enemy religion is conquered or a city is converted to your religion, gain a sum of
Golden Age points.
UU: Multi-barreled Cannon or
Sowar
The multi-barreled cannon would be more expensive than regular Cannon, but once placed, may attack more than once per turn. The cannons themselves were developed by Fathullah Shirazi for Akbar, but I figured this could be another way to highlight Mughal artillery prowess (though I'm not sure just how much the multi-barreled cannons were used).
-or-
The Sowar would be a Dragoon(?) replacement. Would get a combat bonus against cities of rival religions. Really, I haven't come up with anything exciting for this, but it's a bit more justifiable as a UU.
UB: Karkanah
Replaces the Artist's Guild. Contains a slot for Great Works of Art. During Golden Ages, Great Artist production is boosted by 50%.
Under Aurangzeb, these buildings (described by Francois Bernier) made valuable textiles. I kind of mashed it together with his love for calligraphy to work with the UA a little better.
Genuinely interested in how this could be made better. I figured Aurangzeb (and his zealotry) were perfect to make a "one world religion" warmonger Civ
I took another look at Aurangzeb and here's what I came up with:
Aurangzeb
Agra
UA: World-Seizer
Whenever a city following an enemy religion is conquered or converted to your religion, gain
Golden Age points. Conquered cities suffer no resistance if they follow your religion and increase
Unhappiness by 33% less.
UU: Multi-barreled Cannon
More expensive than the Cannon it replaces
c5production: 225), the Multi-barreled Cannon begins with the Logistics promotion, allowing it to attack more than once per turn, and is slightly weaker vs. cities (17 vs 20).
UA: Karkanah
Replaces the Artists' Guild (more expensive, but not sure by how much yet). Contains a slot for Great Works of Art. Grants +1
Faith if the Great Work slot is filled. During Golden Ages, Great Artist generation in this city is increased by 50%.
His UA and UB are a little busier, but I think the design works somewhat better now.
For the UA, I added the no resistance/less unhappiness bit to help emphasize spreading your religion during times of peace. Which gets you more GA points from Part 1 of the UA. I dropped the inquisitors/Great Prophets bit, because while I felt it kinda fit thematically, the same thing could be done more simply by allowing the player to get more Faith instead (I also had conquered cities giving faith equal to combat strength, but dropped that too because I felt it made things too busy).
For the UU, I went with the multi-barrel cannon. Having siege units that start with Logistics is pretty good (I think - if not, can buff more). Making it slightly weaker against cities fits because each barrel would fire a smaller shell, doing less damage each - and also tries to keep them from shredding cities too fast with their ability to fire multiple times.
For the UB, I looked back to the UA. It wants Faith. Though the calligraphy Aurangzeb patronized is a stretch as far as Works of Art, in Islamic traditions, they're much the same as paintings or statues of Jesus in a Christian church. Having the building make only Mughal calligraphy is a bit narrow, but I thought having the Faith apply to any Work in its slot was good enough. More Artist generation for GAs helps fill these slots. I considered having the Faith bonus apply to
all filled Great Art slots in that city, but I'm not sure if that's too strong.
Altogether, I would think the early game would focus on getting a religion and spreading it, before warmongering later on. Or in waves. Whatever floats your boat, really. The secondary focus on Great Artists gives Aurangzeb an outside shot at a Tourism win that usual warmongers may not have, too (opulence of the Mughals!). The increased UU/UB costs (not too much over the originals, I hope), also reflect the rising inefficiency of the later Mugal empire to a degree. I'm really happy with what I've got above, and wonder what some of you fine civ-makers think on a few questions:
1.) Is Logistics + slight debuff vs cities balanced and useful enough for the UU?
2.) How much more than the Artists' Guild should the UB cost (Guild costs
150)?
3.) Should the Faith bonus on the UB apply only to its Art slot or all art slots in the city?
