I have been looking into this... the pop loyalty spread is not as simple as they quote... and I thought Firaxis was being nice for a change.
So here is an ugly WIP table of the distance effect from a cap purely of population... so to explain the graph a 5 population capital will exert -10 loyalty at a distance of 8 tiles... that is mighty strong. Population is the killer here.
I said a few weeks ago, get three settlers in some jungle with builders, settle and chop in pop/granary for a frightening loyalty stab
The thing is most other modifiers are for defence, nothing else really has such a strong effect as pop and more importantly population difference
Has anyone seen a pop formula anyone has come up with yet? When two cities contect this is also not clear.
Settling a city close to a 1 pop city is just fine, settle near a 5 pop city and you flip... simples.
Just think of those minuses on the ground... a mere -2 means you will convert in 50 turns but that city is growing and next turn it could be -4 for 25 turns then 08... nasty.
You are then forced to put in defences like cards which will take up valuable card space and useful governors that could be used elsewhere. Is it really worth it?
Now you may think thats simple but what happens when you have 3 citues exerting -20. That -20 is the most they will exert is my understanding... its not really -60 and so a governor will reduce that to -12, garrison 10, etc etc... the RNDY withyy +2/+4 is now quite helpful in this regard.
All of this is just guesswork to some degree, one is cautious but it looks this way
I have to clean out chickens and I want to play a game today but will post more
I have yet to work look at exactly how a capital effects things. It may be more pop based than capital so taking out big cities and getting starvation and looting amenities will all help lower their loyalty while you are attacking them.
A pop 1 city starts with +20 pressure but does not go all the way out to 9 tiles
This is not the entire list, just what I have got, I have not been all the way through the trees yet, if someone posts other bits I can add them to this an maybe eventually we can have a loyalty page whioch would be useful.
pressure = N * pop * (10 - dist) - 10, capped to 0-20 range. N is 1 for normal city, 2 for Capital.
Pressure from Nearby Citizens -20 = +20
I can confirm that neither the Other column nor the Amenities column change the pressure a city exerts. They only affect how the city is behaving internally. Governors also have 0 effect on sending pressure apart from Amani's Prestige and Emissary promotions.
Occupation -5
Governor placed in the city +8
Government Plaza - +8 loyalty to the city
Audience Chamber -2 loyalty to cities without a governor
Happy +3
Ecstatic +6
Colosseum provides +2 loyalty to every city within 6 tiles.. that amenity boost is also friggin strong.
Government Plaza +8 loyalty to the city
Amani will provide +4 local Amenities with the level 2 promoter promotion.
Amani will give +2 loyalty to all your cities within 9 tiles with the Level 1 Prestige promotion
Amani will give enemy cities within 9 tile +2 loyalty towards your civilization with the Emissary promotion
Starvation, any starvation causes -4 loyalty
Praetorium diplomatic card - governors provide an additional +2 loyalty to the city they are in
Limitanei military card - +2 loyalty for a garrisoned unit
Colonial Offices economic card = +3 loyaly to off continent cities
During a Bread and Circuses project each citizen provides +1 loyalty pressure.
Completing a Bread and Circuses Project provides a one-time boost of +20 loyalty to a city
England: RNDY +2 on Continent +4 off Continent
Holland: Trade Routes to your own cities provide +1 loyalty per turn for the source city
Maphuche: If a Maphuche unit defeats an enemy unit within the borders of the enemy city, that city loses 20 Loyalty.
Zulu: Isibongo Cities with a garrisoned unit get +3 Loyalty per turn, or +5 if it is a Corps or Army.
Classical Admiral Themistocles grants +2 loyalty per turn to a city (1 charge unless Mausoleum)
Renaissance Admiral Magellan grants +4 loyalty per turn to a city (1 charge unless Mausoleum)
All cities within 6 tiles of the Statue of Liberty are always 100% loyal.
Free City +10
City STate +20
A free city will stay free while 2 competing civs have equal pressure upon it.
France one suspects will be rather strong with spies with the level 2 building and 7 spies starting at level 2! You could really cause damage.
