Religion

Religion is based on a new resource called Faith, which can be earned by exploring ancient ruins, constructing religious buildings such as Shrines and Cathedrals, building religious Wonders, and through special abilities (like the Celts' ability to earn Faith from forests or through their Pictish Warrior's ability to generate Faith in combat).

Religions can be customized and developed from a simple pantheon to a modern religion by selecting "Beliefs" that offer specific benefits. You choose Beliefs from a pool (of about 50), and they are unique; choosing a Belief makes it unavailable to any other Religions in that game. A religion may accrue up to a total of five Beliefs over time (though the Byzantines have the special ability to unlock a bonus sixth Belief).

A religion starts out as a primitive animist Pantheon, which is available very early in the game when your civilization has accumulated about 10 Faith. The symbol of a Pantheon is a lightning bolt. A Pantheon has a single Belief chosen from a pool of ~20 Pantheon Beliefs, that provides a basic resource or Faith bonus for certain terrain types. Pantheons do not spread beyond your borders. The amount of Faith it takes to found a Pantheon will increase with every Pantheon that has been founded on the whole map.

Once your civilization has accumulated a certain Faith threshold (depending on game speed), you have a chance every turn to generate a Great Prophet. (When the Prophet spawns, it empties your Faith reserve, regardless of how much above the threshold you had built up.) This Prophet can be used to convert your Pantheon into a full-blown Religion. When founding a Religion, you choose one of the 11 available icons and names (you can change the name), and two more Beliefs, called a Founder and Follower Beliefs, each from a separate pool. When you get a second Great Prophet, you can then Enhance your religion, which unlocks two more Belief slots (called 2nd Follower and Enhancer Beliefs).

The 11 available religion icons are: Buddhism, Christianity, Confucianism, Hinduism, Islam, Judaism, Shinto, Sikhism, Taoism, Tengriism, and Zoroastrianism.

There is a cap on how many Religions can be created in one game (looks like half the total number of civilizations). This limit applies only to Religions and not to Pantheons.

Beliefs

Beliefs are grouped into four categories: Pantheon, Founder, Follower and Enhancer. Pantheon Beliefs offer basic production bonuses for resources and terrain. Founder Beliefs offer bonuses that benefit only the founder of the religion. Follower Beliefs offer city-specific bonuses or special structures that can benefit any city that follows the religion. Enhancer Beliefs give you access to things like cheaper missionaries, allowing you to spread your religion faster. The total number of Beliefs that a mature Religion can have is five. There is also a sixth Bonus Belief, available only to the Byzantines, which can be chosen from all the available Belief types. Once a Belief is chosen, it becomes unique to that religion and cannot be chosen again by a different religion in the same game.

Spreading Religion

Each citizen of a city is either an atheist or is converted to a Pantheon or Religion individually. If a majority of citizens in a city follow a particular Religion, then that becomes the "majority Religion" and the city is said to follow that religion, and will generate religious "Pressure" that extends 10 hexes and will slowly convert citizens of other cities to that religion. Majority religion is indicated by an icon on the city bar (see image at right), and mousing over this icon brings up a tooltip that identifies how many citizens follow each religion in the city, how much religious "Pressure" is exerted by each religion, and whether or not this city is the "Holy City" for a given religion. The Holy City is the city (usually the capital) in which the first Great Prophet founded the religion, and it appears to generate additional Pressure. Ed Beach: "If you, as a founder of a religion, have your Holy City captured, you will lose the Founder benefit. That being said, the conqueror does not gain those benefits, they just cease to exist until you’re able to recapture your Holy City."

Pantheons do not generate religious Pressure, and will not spread beyond your borders. It's not clear how Pantheons spread (if at all) within your civilization; it may be that each of your cities automatically gets 1 or 2 followers of the Pantheon and that's it. These Pantheon followers still remain in your cities when the Pantheon is transformed into a Religion; presumably they are converted by religious pressure over time to the new Religion.

Religions can spread on their own from one city to another within 10 hexes (without regard to national borders), converting one citizen at a time depending upon existing religious pressure. Missionary units can be used to accelerate this process. Inquisitors can be used to "stamp out" a competing religion from a city (called "Remove Heresy"), or can be used passively to prevent the spread of religion to the city in which they are stationed. The costs of both Missionaries and Inquisitors increases with each Era, so the best time to spread your religion is early in the game.

Ed Beach: "The Inquisitors are kind of the anti-Missionaries, where instead of adding religious Pressure to a City, they take it away; but in this case you're taking it away from those other civilizations who are trying to push that religion onto you."

Missionaries have multiple uses before they are expended; an Inquisitor can only be used once. Great Prophets can also be used both to Spread Religion and to stamp it out. Prophets can also build a special Holy Site tile improvement.

In addition to purchasing Beliefs, Faith can be used to purchase unique buildings (like Cathedrals) and units (like Missionaries) that are otherwise unavailable, or to purchase normal Great People (with the appropriate Social Policy for the desired Great Person type: Order for Great Engineer, Autocracy for Great General or Great Admiral, Freedom for Great Artist, Rationalism for Great Scientist, and Commerce for Great Merchant). Rival civilizations will now consider your religion during diplomatic negotiations. During the Middle Ages and Renaissance, these diplomatic modifiers will increase. During the Industrial and Modern eras, these modifiers will decrease. Spreading religion in another civilization's cities will be unwelcome if that civilization has founded a religion of its own, and will incur a diplomatic penalty (especially if you are requested to stop and refuse).

Espionage

A Spy is gained at the beginning of each new era, starting with the Renaissance. Spies can gather information on foreign cities, steal technology, learn enemy war plans, perform counter-intelligence missions, and affect influence with City-States by rigging elections or staging coups. Espionage is conducted entirely through menus; Spies are not actual units that appear on the map. There are three spy ranks: Recruit, Agent, and Special Agent. Each subsequent level makes the spy more effective. A higher ranking spy will steal technologies faster, discover and kill enemy spies that are trying to steal from you more frequently, rig elections in City-States more effectively, and have a greater chance of pulling off a coup in a City-State allied with another civilization. Spies level up when they successfully steal technology from another civilization or kill an enemy spy attempting to steal their technology. If a Spy is killed, you will have to wait a set number of turns before receiving a replacement, who will be at Recruit experience level.

A Spy can slowly affect City-State influence over time (increasing your influence and decreasing others') by rigging elections (which occur in each City-State every 12 turns), which appears to be relatively safe but time-consuming. Alternatively, the Spy can try to trigger a coup, which affects influence immediately, but runs the risk of the Spy being caught and executed and incurring a severe influence penalty.

The first civilization to reach the Renaissance Era unlocks Espionage for all players on the map, awarding each player with one Spy to begin with. England receives a bonus Spy. You are also awarded with an additional Spy when you build the National Intelligence Agency (which is a National Wonder).

Cities are rated as targets for Espionage by a "Potential" rating. Ed Beach: "Potential is calculated based on the Science output of the city (obviously, higher is better), as well as the defensive buildings contained in the city, which can slow down a spy quite a bit. Once you’ve established ’Surveillance‘ in an opponent’s city, the potential will be displayed, so you can make a more educated decision about staying, or redeploying somewhere better." From the tooltip on Potential: "You always know the potential of your own cities. If you are in the lead technologically, you should consider protecting your high Potential cities. There are two ways to do this. You may move your own spies to your cities to act as counterspies that have a chance to catch and kill enemies spies before they steal a technology. You may also slow down how quickly enemy spies can steal technologies by constructing buildings like the Constabulary, Police Station, and the Great Firewall."

From the tooltip for the button to Move a Spy: "When a spy is directed to move to a new city, it takes a number of turns before it becomes fully effective. If the spy is moving to its owner's city, it will begin counter-espionage to uncover and kill enemy spies. If a spy is moved to a city that is owned by another civilization, the spy will begin trying to steal technology from that civilization. A spy can only steal from a civilization that knows any technology that the spy's owner does not. If the owner of the city has a spy defending the city, your spy has a chance of being discovered and killed. This may strain diplomatic relations! If the spy moves to a city that is a City-State, the spy will attempt to rig the elections to increase your influence over the city-state."

Songhai: River Warlord changed to: "Receive triple Gold from Barbarian encampments and pillaging Cities. Land units gain the War Canoe and Amphibious promotions, strengthening them while embarked."

Enhanced Diplomacy

Foreign civilizations will now consider your Religion and the Social Policies you've chosen when deciding whether or not to like you. Religion will be more important early in the game; the diplomatic modifiers for Religion will increase during the Medieval and Renaissance ages, but will then decrease thereafter. After the Renaissance period, the major impact on diplomacy will be which of the Industrial-era Social Policy trees you've chosen: Freedom, Autocracy or Order.

Information obtained through Espionage can also be used in the Diplomacy system (such as informing a friendly civilization that another civilization plans to attack them). Diplomatic deals can now be renewed (or renegotiated) instead of simply ending after a certain number of turns.

You can once again found Embassies with other civilizations. Embassies allow visibility of the other civilization's capital, and are required for Defensive Pacts and Open Borders agreements. Going to war will dissolve an embassy.

The negative diplomatic modifier for "trying to win the game the same way as us" has been removed. Diplomatic modifiers are now color-coded according to how severe (or beneficial) the effect is.

Revised Technology Tree

The tech tree has changed. The Classical era has been expanded to 2 tiers, and the post-Industrial eras have been expanded into: Modern, Atomic, and Information eras. There are 8 new technologies.

New City-State Types

New types include Religious City-States which provide Faith, and Mercantile City-States that provide a Happiness bonus and unique luxury resources such as Jewelry and Porcelain. The Influence system has changed, providing more quests (up to three per City-State at one time), and reducing the effectiveness of cash gifts. There are new quest types such as "generate the most Faith in 20 turns." The UI for the Influence meter on the city bar has changed, and now displays the four distinct stages of Influence in one meter. At right, Antwerp is an example of a Mercantile city-state, and below right, Jerusalem is an example of a Religious city-state. A helpful "Find on Map" button has also been added. to the UI.

City-States will no longer request that you conquer a rival; instead you may now "Bully" or demand tribute from a City-State. By moving a military force close to a City-State's borders, you can intimidate them (the icon will turn orange) and you will unlock the option to "Ask For Tribute", in which you can demand gold or a worker, with appropriate Influence penalties. Bullying a City-State will reduce your Influence and cause that City-State to cancel any available quests that it has offered you, and may incur diplomatic penalties with any civilization that has pledged protection to that City-State.

Mercantile City-States: Antwerp, Cahokia, Colombo, Genoa, Hong Kong, Marrakech, Singapore, Tyre, Zanzibar, Zurich
Religious City-States: Geneva, Jerusalem, La Venta, Lhasa, Vatican City, Wittenburg
Other new City-States: Jakarta (Maritime), Lisbon (Maritime), Prague (Cultured), Manila (Maritime), Milan (Cultured), Mombasa (Maritime),Valetta (Military), Yerevan (Cultured)

Combat Changes

Units have more health and so may last longer in combat (health has been increased from 10 to 100). According to Ed Beach: "In Civilization V, one unit could kill another unit of the same strength with about two hits (roughly 4-8 damage per hit). Under the new 100 point system, it would take approximately 3-4 hits (at around 24-36 damage per hit)." Accordingly, the mechanics of combat have changed significantly, and the Combat Strengths of many existing units have been changed. Healing rates have increased x10.
There are now "melee" naval units that attack by ramming or boarding enemy units at close range. Melee naval units can attack other naval units and coastal cities, but NOT land units on the coast. They also get promotions that allow them to pillage gold while attacking cities. The Trireme is now a melee unit. The Destroyer is now a melee unit; the Battleship is still ranged. The Caravel is now a melee unit, and upgrades to the Ironclad, which is also melee.
Embarked land units now have "Defensive Embarkation," which allows them to defend themselves when attacked via melee, and can stack with a naval unit for protection. There is also a new Great Admiral unit that can heal nearby friendly naval units.
There are three new ranged units to fill the gaps in the various eras, so that you no longer have to upgrade Crossbowmen to Riflemen (making their ranged promotions useless). The new ranged upgrade progression goes:
Archer -> Composite Bowman -> Crossbowman -> Gatling Gun -> Machine Gun.
Units can still heal themselves in lieu of a promotion, but this instant heal can now only be 50% of their maximum health.
There is no longer a "Garrison" command; any unit in a city is automatically considered garrisoned, and may take normal actions without giving up the Garrison defensive bonus to the city.

New Scenarios

Three new original scenarios are included.

Fall of Rome

Play as either Eastern Rome or Western Rome trying to fend off the barbarians OR as one of the barbarians themselves. Eastern and Western Rome have to select Social Policies that actually have negative effects, so they will get weaker over time.

Into the Renaissance

Grow your medieval kingdom into one of the great nations of Renaissance Europe, fending off outside invasions from Mongols and Ottoman Turks and fighting the religious wars of the Crusades and Reformation!

Empires of the Smoky Skies

Build flying airships and huge landship steam tanks from the unique tech tree of this Victorian science-fiction scenario, and use them to spread your empire across the pre-industrial world. The scenario starts at the beginning of the Industrial Era, and requires the player to hold 3 of 5 Honourable Titles awarded by the League of Empires for five consecutive turns.

Five civilizations: Eruch (Cyrus Rotheram), Vedria (Luther Griggs), Orlin (Ignace Curlin), Pulias (Octavius Cutler) and Dalmace (Clinton Alderdice).
Custom buildings, new resources, new units
Steam Era and Airship Era

Victory Conditions: Empires compete in five categories; be the best in a domain to earn an Honourable Title. To see the specifics of each Title, and monitor your progress, check the League of Empires screen. The first empire to hold three or more Titles will control the League and win the game.

Defender of Progress: have the most land and airships
Grand Philanthropist: have the most world and national wonders
Captain of Industry: have the highest production
Lord of Refinement: have the most social policies
Master of Wealth: have the highest total gross gold income

Special Rules: Players begin with all technologies up through Steam Power. The tech tree after Steam Power has been altered significantly, giving players the ability to construct Airships, Landships, and new buildings. Barbarians ("Luddites") are enabled, but do not have access to advanced units. Social Policies have been rearranged. Religion has been disabled, as have religious and military city-states.

New Units

There are 27 new units in the expansion. The following list has 28 entries; the Infantry unit has been split into WWI and WWII versions, but this is counted as only one "new" unit. Note that the Cost numbers listed below may be out of whack, because we don't know what game speed settings the various screenshots and videos are using.

New Resources

All 7 of these new resources are Luxury Resources, providing +Happiness in addition to the tile bonuses. Two (Jewelry and Porcelain) are not available on the map, but are only provided by Mercantile City-States.

Truffles

Improved by: Hunting Camp
Bonus: +2 Gold
Found on: Forest, Marsh, Jungle

Crab

Improved by: Fishing Boats
Bonus: +1 Food, +1 Gold
Found on: Coast
Notes: The "net" cast from the Fishing Boats is a box-shaped crab pot instead. Crab is a tradable luxury resource.

Citrus

Improved by: Plantation
Bonus: +1 Food, +1 Gold
Found on: Grassland, Plains
Notes: Citrus is a tradable luxury resource.

Salt

Improved by: Mine
Bonus: +1 Food, +1 Gold
Found on: Plains, Desert, Tundra
Notes: A tradable luxury resource.

Copper

Improved by: Mine
Bonus: +2 Gold
Found on: Grassland, Plains, Desert, Tundra, Snow
Notes: Copper is a luxury resource.

Porcelain

Yield: +2 Gold
Notes: A manufactured luxury resource unique to Mercantile City-States. This resource is not located on the map, but is awarded by the City-State to its ally civilization. It does appear that conquering a Mercantile City-State also give you access to the resource; in this screen the Dutch player has annexed Marrakech, but the Porcelain shows in the tooltip for city tile, and in the Happiness menu, the player is receiving a Happiness bonus for Porcelain.

Jewelry

Yield: +2 Gold
A manufactured luxury resource unique to Mercantile City-States; it is produced by the city-state rather than found on the map, similar to Porcelain.

Tulips: Several early previews claimed that Tulips are a manufactured luxury resource created by the Netherlands Polder unique improvement. However, this has not been verified via in-game screenshot; the portion of the Polder Civilopedia entry we've seen does not mention Tulips, and the list of font icons obtained through the beta patch does not contain a resource icon for Tulips, so it seems likely that either these previews were in error, or Tulips have since been removed.

New and Changed Improvements

Ancient Ruins can now provide 60 Faith.

Polder

Yield: +3 Food
Technology: Guilds
Built on: Marsh, Floodplains
Notes: A unique improvement for the Netherlands. It increases food production in Marsh or Floodplain tiles. Polders do not produce Tulips, as erroneously claimed in a few foreign previews. A "polder" is an agricultural area of land reclaimed from marsh, lakebed or the sea, surrounded by dikes (and a windmill to pump the water out as it seeps back in).

Holy Site

Notes: An improvement created by a Great Prophet. It adds +6 Faith production to the tile.

Trading Post

Technology: Guilds
A new graphic for the Trading Post (as indicated by the mouse-over tooltip). The Trading Post is now available with Guilds (a new Medieval era technology) instead of Trapping.

Citadel

Notes: The Citadel, which is a special Fort created by sacrificing a Great General, appears to have received an additional ability. According to the translation of this tooltip: In addition to providing +100% defensive bonus for the unit stationed on it and doing 30 damage to any enemy units that end their turn adjacent to the Citadel (not cumulative with other Citadels), it now appears that the Citadel, when placed, acts like a Great Artist's Culture Bomb, extending the civilization's borders by 1 hex around the Citadel, and potentially incurring a diplomatic penalty if this takes territory away from a neighbor. The Citadel can be placed within 1 hex of your borders (but presumably only in friendly or neutral territory as with the Culture Bomb).

New Natural Wonders

Mount Sinai: +8 Faith

Sri Pada: +2 Food, +4 Faith, +2 Happiness

Mount Kailash: +6 Faith if worked, +2 Happiness if within your borders.

Uluru/Ayer's Rock: +2 Food, +6 Faith
