-- Civics
- Social Policies are now replaced with Civics, which in essence belong to their own seperate tech tree and utilise Culture.
- Like Technologies, each individual Civic has their own unique in-game sidequest. Like techs, some of these you'll get through playing the game regularly, and some will require some extra effort.
- Advancing throughout the Civics tree allows you to unlock buildings, wonders, and other bonuses
-- Policies
- Advancing throughout the Civics tree allows you to unlock new policy cards you can have in your "deck"
- New "Deck" mechanic. Throughout the game you gain Policy Cards which you can slot in and out of your deck for specialisation purposes.
- The Policies you unlock give you a new card to slot into your "Deck".
- Policies come in four flavours: Military, Economy, Diplomacy, and "Wild".
- You can change your policy cards for free every time you unlock a Civic, or with gold whenever you want.
-- Governments
- Advancing throughout the Civics tree allows you to unlock new forms of government.
- In addition to providing certain built-in bonuses, each government has a different configuration of slots for policies. (i.e One government might have more "Military" slots, whereas another might not have slots for Military policies at all and instead focus on Economy and Diplomacy.)
-- Civilizations
- Civs will have four unique components. For example, America has a Unique Ability alongside 2 Unique Units and a Unique Building
- Added Egypt's Leader and America's Uniques
-- Other Mechanics
- There are no more Workers. Instead you have builders that disappear once they complete a task.
- Builders construct their projects immediately, but only have three charges.
- City-States are back
- New "Lens" System
- There are now new lenses that are essentially UI filters that get draped over the map that help the player analyze data
- For example, there's now a religion lens which will color-code the dominant religions on the map.
- Trade Routes allow you to gain information about your rivals as a form of early espionage
- Barbarians can generate scouts now, which in turn look for targets to harass.
- Barbarians are much more intelligent and now have purpose (don't just endlessly wonder)
-- Natural Wonders
- Natural wonders can span multiple tiles
- GBR is back and Pantanal is new and spans 4 tiles.
