RELIGION

New set of eight major religions:
- Judaism (Literature): scripted spawn possible if Jerusalem or nearby city is independent, shrine: Temple of Solomon
- Orthodoxy (Ethics): scripted spawn possible in a Jewish city, shrine: Church of the Anastasis
- Catholicism (Doctrine): scripted spawn when more than half of all Christian cities are not controlled by Orthodox civilisations (Great Schism), shrine: Saint Peter's Basilica
- Protestantism (Printing): only founded by a Catholic civilisation (Reformation), shrine: All Saint's Church
- Islam (Theology)
- Hinduism (Calendar): shrine: Vishwanath
- Buddhism (Philosophy)
- Confucianism (Contract)
- Taoism (Aesthetics)
- Zoroastrianism (Priesthood): shrine: Adur Farnbag
Great Schism occurs when Catholicism is founded
- Largest city not controlled by an Orthodox civ becomes Catholic holy city
- Cities in Orthodox civs remain Orthodox
- Other cities convert to Catholicism if they are closer to the Catholic than to the Orthodox holy city
Reformation occurs when a Catholic civilisation discovers Printing and founds Protestantism
- Catholic civilisations choose to embrace, tolerate or oppose the Reformation
- Embrace: civilisation and most cities convert to Protestantism, receives gold based on number of removed Catholic buildings
- Tolerate: civilisation remains Catholic, only some cities convert to Protestantism
- Oppose: civilisation remains Catholic, no cities convert to Protestantism, war is declared against all Protestant civilisations
Religions can only be founded in their core or historical regions
Pagan religions:
- Instead of starting as "no state religion", civs have their own pagan religion (e.g. Olympianism, Shinto, Tengri)
- Pagan temple specific to their pagan religion
- Unlike major religions, pagan religions have no temple/monastery/cathedral buildings, missionaries, shrines, or additional happiness and culture
- The spread of a major religion (excepting minority religions like Judaism) removes the pagan temple from a city
- If the religion that removes the pagan temple is your state religion, it is replaced by a temple for that religion
- Civilisations with a state religion treat pagan religion as a different religion and will have a negative opinion of them
- Civilisations with a pagan religion do not treat civs with a pagan or major state religion as having a different religion and will not have any opinion modifiers (positive or negative)
Unique Religious Victory: different victory goals depending on your state religion

  - Chosen People: Have a total of 15 Great Prophets, Great Scientists and Great Statesmen in your cities

Completely redesigned religion spread rules:
- less randomness
- religions spread gradually around cities that already have them, not just holy cities
- religious buildings influence religion spread
- regions influence which religions can spread more easily (including missionary success chance)
- special mechanism to spread religions over long distances or to different continents
- only missionaries of proselytizing religions (Buddhism, Christianity, Islam) can spread in cities of civs with a different state religion
- to adopt a local religion (Judaism, Taoism) you need to control its shrine
- religions can disappear from a city if that religion cannot spread to the city under current circumstances (e.g. after owner or state religion change) or if too many religions are in a city, higher chances of disappearance right after a new religion has spread to the city
- religious buildings disappear with their religion
- new formula to calculate global religion presence
Non-state religions create additional unhappiness unless you are running Secularism
Related religions create reduced diplomacy penalties and no unhappiness from non-state religions:
- Hinduism and Buddhism
- Confucianism and Taoism
Spread of religions removes Pagan Temples and replaces it with the temple of the new religion in case it is the state religion
Christian civs start with their historically appropriate religions unless it is not already founded (e.g. Protestantism for Netherlands, but Catholicism if Protestantism is not yet founded)
State religion of colonial civilizations depends on the dominant religion in their core
Religion specific names for all religious buildings

CORPORATIONS

Corporation headquarters and executives removed, corporations spread on their own to cities that fulfill their requirements
Corporation spread influenced by amount of consumed resources, civics and buildings in the city
Silk Route and Trading Company only spread to appropriate historical regions
Corporations create unhappiness and pollution based on the number of resources they consume
New corporations:
- Silk Route (Currency): Silk, Cotton, Incense, Camel -> food, gold
- Trading Company (Exploration): Spice, Sugar, Ivory, Banana, Coffee, Tobacco, Tea -> food, gold
- Cereal Industry (Biology): Wheat, Rice, Corn -> food
- Fishing Industry (Refrigeration, Corporation): Fish, Clam, Crab -> food
- Textile Industry (Thermodynamics): Sheep, Silk, Cotton, Dye -> gold, production
- Steel Industry (Metallurgy): Iron, Coal, Copper, Aluminium -> production
- Oil Industry (Refining): Oil -> gold
- Luxury Industry (Consumerism): Gold, Silver, Gems, Marble, Pearls -> gold, culture
- Computer Industry (Computers): Copper, Aluminum, Oil -> research

EVENTS

New event: Radiation Leak. Requires Nuclear Plant. Options:
- Refit the nuclear plant: costs gold, very low chance of nuclear meltdown
- Ignore the problem: causes unhappiness, low chance of nuclear meltdown, event may continue
- Abandon nuclear energy: all nuclear plants become obsolete
Interstate event: now replaces all Roads and Roman Roads on flatland with Highways
Royal Wedding event: can only be triggered when government is not State Party or Democracy

STABILITY

Stability checks are now triggered by certain events (e.g. discovering a technology, changing civics, losing/acquiring a city, starting wars, making peace)
Stability scores are not permanent anymore, but instead calculated for every stability check (no permanent stability hits anymore)
Only stability levels are stored: Collapsing, Unstable, Shaky, Stable, Solid
Stability is divided into five categories:
- Expansion: overexpansion (population outside vs. inside of core), recent expansion, recently razed cities
- Economy: economic growth
- Domestic: happiness, civic combinations, contemporary and outdated civics, religious unity
- Foreign: vassal stability, defensive pacts, foreign relations
- Military: war success, war weariness, barbarian losses
After a check, the stability level can increase or decrease based on your stability score result
If stability does not improve when on Collapsing, a complete collapse occurs
Collapse after overextension triggers collapse to core instead of a complete collapse for AI civilisations

DIPLOMACY

Congresses:
- Triggered either periodically or when a large war ends
- Players can claim cities or request to settle free spots
- After a war, the winners can claim cities from the losers
- The entire Congress is resolved in one turn
- When voting on a city claim, camera moves to the city in question
- If an AI civ is undecided on your claim or a claim on one of your cities, you can attempt to influence them using gold or espionage
- City assignments by the Congress can be refused, which might lead to war against the civilizations that voted yes
- Voting AI takes its relationships, own interests and the legitimacy of a claim into account when voting on claims
- Congresses establish contact between all participants
General Apostolic Palace and United Nations rules:
- Votes are now proportional to the square root of your (state religion) population, to give smaller civs more weight
- When attempting to win a Diplomatic Victory, your own votes and those of your vassals do not count (you need to win a majority among the other civilizations)
- Resolutions that affect all members do not fail if one member defies it, instead only defying civilizations are not affected
Apostolic Palace:
- Elections are initiated by building Saint Peter's Basilica
- Only civilizations with Catholic state religion are members and allowed to vote
- Renamed "Declare War" resolution to "Crusade": valid targets are non-member at war with members (defensive crusade) or non-members that control the Catholic shrine or holy city (offensive crusade)
- Added "Collect Tithe" resolution: all members pay 10% of their treasury, the Pope receives half of it
- Added "Send Inquisition" resolution: the Pope receives additional espionage against the target
- Added "Excommunication" resolution: the target player loses membership an receives unhappiness as if they had defied a resolution
United Nations
- Only the four civilizations with the highest military power can defy resolutions (Security Council)
- Added "Decolonization" resolution: cities on other continents can be forced to be released to independents
- Added "Self-Determination" resolution: if a civilization can be released, it can be enforced by the UN
