Various suggestions for stuff!
Yay, free suggestions.
Hetmanate: UA: Rightful Liberators: Recieve Great Person points in the Capital (100 base, increased by 50 every Era) upon liberating a city. Pillaging tiles gives a boost of Food and Production to the nearest city. (Basically I didn't like the name of the UA so a better one, and a nifty bonus to help fit with it.)
Wooooo, I will not name those filthy rebels "rightful".

I made Hetmanate, because they fit to pillaging trait I truely wanted. It's funny, because most people recognize Cossacks as "cavalry", while their favourite activity was plundering Black Sea coast. They were pirates of east Europe, arr.
Anyway, trust me that Hetmanate doesn't need a buff (neither Great People fits their theme). Very strong civ with early warmongering potential.
Though, I will look for a better name (Looting/Plundering/Black Sea Scourge/Ravagers)...
Jerusalem: UA: Rename UA to "Kingdom of Heaven", just so that it isn't so similar to the UU, and also, technically speaking, the Kingdom of Jerusalem didn't take part in the crusades so much as formed as a result of them.
Ok. To be honest, I wanted to name it something like "centre of Earth" (in latin?), related to fact that Jerusalem was believed (still is?) to be centre of Earth. Quite logical looking on medieval maps (+geocentrism). Couldn't find proper sentence.
Papal States: Swiss Guard should give +1 Culture for every era past the Medieval, and never go obsolete, but obviously loses that bonus upon becoming a Lancer. Church should be renamed Basilica.
They were once never obsolete, but AI had this tendency to spam it (low production unit, perfect for marching on enemy tanks). I am quite sceptical about buffing garrison effect, because... AI doesn't handle it now. I would have to spent a lot of time to write the script so AI would keep unupgraded SG and garrison them.
Isn't Basilica a church? Though If I remember correctly, I had seen Basilica mod (new Belief) and that's why I didn't named it so.
Sioux: UA: Seven Council Fires: +1 Happiness from every 12 owned tiles. Every non-Tenet Social Policy adopted will cause a source of Bison to spawn on a random flat Grass or Plains tile. (same Bison from the BNW Conquest of the New World scenario, Tipi camps can be put on these too but won't spawn units)
I somehow do not feel the pressure to add Bisons (if anything I would made (1 Bison per Sioux Civ) that appear randomly on plain tiles. It would travel from city to city, having quite decent amount of food/production). Obviously, considering that 1 turn is 20 years it has little sense to introduce migration mechanic.
Sioux are already top tier and I don't feel to buff them more.
I think Happy Hunting Ground isn't so bad name, is it.
Mali: Rename UA to Splendor of the Mansa, because I think that sounds nicer. I'm still tempted to complain about slavery stuff but eh, the UB is pretty neat and accurate and I can't think of anything else it could even be called so w/e.
It will be done (though it is not worthy a update).
I have made some changes (not updated yet):
~Romania UA is reverted to the City-States' one
~Cherokee UA no longer gives techs; It simply doubles the science from Trade Routes.
~Cherokee UB no longer provides GW points
~Cherokee flavours will be changed to represent more their great achievements
~Scythians are simplified:
UA - Horse Resource Doubled. Mounted units generates 1 Production and 1 Happiness (in nearest city).
UB - 2 specialist slots (3 food, 2 production)
Other than that, I always wanted to make this UA:
-Great Scientist, Merchant and Engineer have separate meters.
If I will find civ fitting this trait, can I count on you making DoM and Diplo text?
