Civilization VII

Sid Meier's Civilization VII (often referred to as Civilization VII or simply Civ7) is a 4X Strategy video game and the seventh main series installment in the Civilization series. The game was developed by and released on Microsoft Windows, OS X, Nintendo DSGo, and Linux on November 22nd, 2024.
In Civilization VII, the player leads their chosen civilization from the dawn of agriculture through to the far future, hoping to achieve one of many victory conditions. The player must carefully handle many different variables and react to changing conditions, managing research, diplomacy, exploration, expansion, development, and conquest. The game is heavily based upon Civilization VI, retaining many of its changes, while also adding new features, such as new Tribe and Plague systems, a revamp of the combat system, and the return of some previously removed systems like the World Congress.

When released, they will revert to a City-State if one originally, or can return to their original Civilization. Terra nullius introduces the option of releasing previously Civ-owned cities as independent City-States.

==Resources==
Resources are a big focus in Civilization VII to a higher degree than ever before. Obtaining and processing Resources is now a large key to maintaining a large and powerful empire. This fuels expansion and rewards those who colonize and conquer, or those who bargain and buy.
*Once Industrialization hits, Iron and Coal become main focuses, and the player can begin building Manufacturies to transform resources into Products.
==Settlers==
*Settlers are now a Class of Unit, rather than a single type. They have the following options, depending on the Unit:
**Establish a City on the tile they are currently on, after which they will be destroyed.
**Inhabit an already Established City, raising its Population by some amount
**Debate an adjacent Settle Class Unit from another Civilization, lowering that Unit's Wellbeing Score
*Each Settler Class Unit has a Wellbeing Score, the initial value of which depends on the Type of Unit; later Settler Class Units start with much more. 
**This Score automatically goes down for every Turn ended outside of the player's territory, falling quicker on Tiles that cause Attrition like Desert
**When a Settler Class Unit's Wellbeing score is reduced to 0, it is automatically destroyed
**The Wellbeing Score affects Loyalty of the City established by the Unit, as well as the Unit's effectiveness in using the Debate action
*After a City is conquered, an amount of Refugee Units are released equal to or less than the Population lost
**Refugees may only Inhabit and may not Establish
**No Refugees are released when a City is Razed
*Each Player, including starting City-States, starts their first game with one Settler with the unique Attribute Dawn of Civilization, which allows them to Establish the Original Capital of the Civilization
==Loyalty==
*When a Civilization's City's Loyalty falls to a low enough value, it becomes a City-State
*When a City-State's Loyalty falls to a low enough value, it joins the Civilization which exerted enough Loyalty Pressure
==Technologies/Civics==
* and , collectively called Developments, must now be 'spread'. Upon being researched, the city with the highest / output instantly recieve the Tech, and it will begin to spread to the rest of the empire. Cities with highest / outputs will acquire these Developments faster, as will Cities that are closer too and/or have a City Connection with another City that has the Development.
**Any Developments researched instantly for free by a Great Scientist or Wonder will instantly spread to all cities which have the prerequisite Developments.
**Developments which have non-City specific effects must be in 75% of all Cities to work. Other effects, like building Buildings, Improvements, Units, or Districts, can only be performed by Cities with the Development.
**New Cities which are founded start with the Technology of whichever city created the Settler at the time when the Settler was Produced.
**Certain boost the spreading of Developments, and the instantly spreads all Developments to all Cities as after it is researched.
*The and trees have been completely redone as shown below.
**In order to start researching a Development, all of the Developments on the top sides must also have been researched completely.
 
 
==Victory==
*The in Civilization VII can be achieved by becoming the dominant . This occurs when at least 30% of all Cities have the same of the capital, and over 80% of all Cities have a to that of the .

*Environmental damage returns, expanding upon the Introduction system added in Terra nullius
**Rapid Deforestation and Pollution can occur which result in loss of either Production or Growth. Ecologists can be produced to fix the issue, and the Environmental Damage Proposal at the World Congress can be used to punish those who damage the environment.
**Nuclear Fallout reappears, and it can no longer be cleared with any amount of time. Usage of Nuclear Bombs and the ensuring Fallout results in large diplomatic penalties.
**The Hazmat bonus nullifies damage suffered by units in Fallout who have not attacked on the same turn as they would be damaged. It is granted to all units generated in a city with a Nuclear Shelter.
*Economics
** output is now primarily determined by the of a Civilization
**The higher the rate, the more will be generated from Economic Activity. However, a higher rate will also generate more 
**Affected by

*Trading system revamped
**Trade Routes return, but are no longer reliant upon specific trading Units to function.

**Limit on number of Trade Routes is now decided city-by-city
**Trade Routes can now involve trading for other items, like , Resources, Products, or even 
**Intracivilizational Trade Routes now generate based on 
**Trade Routes naturally spread things such as Technologies, Civics, and most importantly, Plagues.
*New Corporation system
**After researching specific Techs, new Products are unlocked
**After a certain amount of time, Corporations appear to produce these Products, or can be established by the Civilization
**Luxuries can be moved to the city with the Corporation and it will produce new Products from it, that provide more happiness than normal and generate more 
**These Products can also be traded to other Civilizations for much more Currency than would otherwise be earned from the pure Luxury
==Civilizations==
These 25 Civilizations came with the original version of the game without any DLC and are compatible with any version. Later DLC Civilizations will only be compatible with Versions of the game that come afterward, e.g. the Iroquois cannot be used without Terra nullius.

Strategic resources are different, however; in addition to the effects on Yields, Strategic Resources also provide a limited quantity of resources with which Units or Buildings may be constructed. In addition to the effects on Yields, Luxury Resources also provide a limited quantity of resources which provide Happiness to the City and can be Traded or turned into Products.
