シヴィライゼーション IVは、限られた初期リソースから文明を構築することがプレイヤーの主な目的である、ターンベースの戦略ゲームプレイに4X帝国構築モデルを使用します。ほとんどの標準的な長編ゲームは、紀元前 4000 年の入植者ユニットおよび/または都市ユニットでプレーヤーを開始します。シリーズの他のゲームと同様に、デフォルトでは、プレイヤーがゲームを完了するために追求できる 5 つの目標が他のすべての文明を征服し、ゲーム世界の土地と人口の圧倒的多数を支配し、最初の寝台船を建造して海に送ることです。アルファ ケンタウリ星系、少なくとも 3 つの異なる都市の「文化評価」を「伝説」レベルに上げる、または国連による「世界のリーダー」人気コンテストで優勝する。ゲームの制限時間に達し、ゲームAI プレーヤーを含むどのプレーヤーもそれまでの目標を達成していない場合、合計ゲーム スコアが最も高い文明が勝者として宣言されます。以前のシヴィライゼーションゲームから大きく離れたのは、 Numerical Design Limited (NDL)のGamebryoエンジンに基づいてゼロから作成された新しいグラフィック エンジンです。
このゲームは批評家の称賛を受け、ターンベースのストラテジー ジャンルをリードするビデオ ゲーム プロデューサーの模範的な製品として歓迎され、史上最高のビデオ ゲームの 1 つとして挙げられています。シヴィライゼーション IVは 2008 年までに 300 万本以上を売り上げ、いくつかのゲーム オブ ザ イヤー賞を含む複数の賞を受賞しました。そのタイトル曲「Baba Yetu 」は、グラミー賞を受賞した最初のビデオ ゲーム音楽でした。シヴィライゼーション IV: ウォーロードとシヴィライゼーション IV: ビヨンド ザ ソードの2 つの主要な拡張がリリースされ、スタンドアロンの拡張パックであるシヴィライゼーション IV: コロニゼーションも 2009 年に 1 つのリリース エディションに統合され、シド マイヤーズ シヴィライゼーション IV: コンプリートというタイトルが付けられました。版。

ゲームプレイ
Civilization IV follows some of the 4X model of turn-based strategy games， a genre in which players control an empire and “explore， expand， exploit， and exterminate”， by having the player attempt to lead a modest group of peoples from a base with initially scarce resources into a successful empire or civilization. The condition for winning the game is accomplished through one of the five ways: militarily defeating all other civilizations in the game world， controlling over two-thirds of the game world’s land and population， building the first spaceship in the Space Age and sending it to Alpha Centauri， having the most dominant Culture ratings over other civilizations， or becoming “World Leader” through the United Nations votes. Additionally， there are multiple game scores for each civilization throughout the game based on the actions of each civilization and a number of different factors， allowing for a win condition based on the total of these points if the game timer runs out. The game can be played in multiple modes: as a single player facing against one or more computer-controlled opponents， in hot seat mode， or through online multiplayer games.
As with other turn-based strategy video games， the player can customize the look and feel of their game world as well as the difficulty of any game AI players before the game starts. Each map space has a terrain type， such as plains， tundra， or desert， that affects the available resources players can extract from their environments and the movements of certain units through that terrain. The player is then given a total of 18 different civilizations to choose from， each with their own pros and cons， plus a leader avatar， an initial set of civilization technology， and any units unique to that civilization. When the game starts， however， it chooses random locations to place across a predefined square grid map. Like other strategy games， Civilization IV has a fog of war feature， in which unexplored territory remains darkened and territories without any units stationed on its designated square is shaded with darker colors.
ユニットと戦闘
Example of some of the units and 3D graphics unique to
Civilization IV.
Most units that the player can generate and use are military units， with certain attributes such as combat strength and movement rate particular to each military type. Each unit can gain experience through combat， which later translates into promotions that the player can use to assign military units new bonuses. Initially， most combat takes place on land， but further advancements in the game’s technology tree can allow the player to build ships and planes with which to fight battles on sea and in the air. Any number of units can be stacked onto a single space and move as a group if so assigned， but the overall combat phase is resolved by one-on-one unit battles.
Combat is initiated when moving military units are moved onto the square occupied by an opposing force’s military units and cities， and combat is then resolved with calculating statistics of each unit combined with some random chance. Defeated units are removed from the game (apart from workers and settlers， which are captured by the attacking force)， and any attacking units that are able to defeat the last defending military unit on a space will move to occupy that space. If the space is occupied by a city the player may choose to occupy and capture the city as their own or raze it. Other than combat， military units can also be assigned to fortify a specific space， perform sentry duties， destroy enemy city improvements， or explore the game world.
Non-military units include settlers who are used to found cities， workers who are used to improve space and gather resources， spies who can perform counterintelligence and espionage， and religious missionaries who can be sent to convert different civilizations and cities. Also， with the Beyond the Sword expansion， new units are added such as executives， who can spread corporations to new cities. Throughout the game， players may also generate a special unit called a “”Great Person””. These are named after historical figures and can be used for one-time advantage boosts in various ways; examples include Great Engineers who increase overall production levels and Great Scientists who improve technology. Assigning inhabitants of cities to work as ‘specialists’ (scientists， engineers， artists， spies， merchants or priests)， building certain wonders or discovering certain technologies can improve the rate at which Great People are generated. Great Generals are generated when a player’s forces achieve a certain number of victories， and can be used either to give a small amount of extra experience to all units trained in a city， or a very high level of experience to one unit. However， like other units， Great People of all kinds can be attacked and killed before the players can use them.
リソースと建物
Once a city is founded， it will automatically begin extracting resources from surrounding spaces; the amount of spaces it can extract from is determined by the city’s population size. The game automatically allocates the spaces a city uses and how its resources are maintained as the city grows， but the player is free to manage the city directly. This feature can be utilized to turn a part of the population into one of several specialized occupations; at the cost of having one less space from the city， these specialists increase gathering and production of the resources of their targeted specializations.
Each city can only produce one military unit or one building at a time; any additional units or buildings are placed into a queue. The rate of construction is determined by the amount of material collected from the surrounding spaces; players can also choose to speed production by sacrificing gold or population if they adopt the required governmental policy; called civics. The player can instead specialize the city towards gathering a particular resource instead of constructing additional units or buildings. Also， in order to produce some units or buildings， certain resources must be collected within the empire and connected to the empires trade network by roads or harbours (for example， horses are needed for mounted units， and iron for swords， while stone or marble increase production of certain Wonders.).
Buildings perform any number of different functions depending on building type; for example， early buildings such as granaries improve food storage to boost the city’s growth and barracks produce better military units， while later buildings such as factories increase general production levels. There are also a number of unique buildings throughout the game. Most notable are World Wonders， which can be accessed through research nodes in the technology tree and construction through the worker unit. World Wonders provide advantages that are unique to each civilization， as they are limited to only one or two players.
Through buildings and specialists， each city also generates the “”Culture”” resource that contributes towards both the area upon which the city can influence for extracting resources and the overall civilization’s cultural value. When two cities of different civilizations are adjacent to each other， the culture values of each city influences the space they can control; it is even possible that a city close to another civilization’s city will join that civilization if their culture is strong enough. The high levels of culture gathering and attainment are also one of the default conditions that can be used to win the game.
テクノロジー、政府、宗教
A screenshot of
Civics option menu in Civilization IV Once the first city has been founded， the player can select their first technology node from the game’s technology tree to research， once the required number of research points have been accumulated， the technology is obtained. As with other types of technology trees， more advanced technology nodes require the research of other previous technology nodes. The player can also select a future technology and immediately place into the game queue any technology nodes between the current technology level and the specified technology node. Technology can also determine another win condition; several endgame technology nodes are required to develop a colony ship to reach Alpha Centauri.
Within the technology tree are technology nodes relating to government civics and state religions， each with their own pros and cons. The player has the option of selecting which set of government civics or state religions that the player wants their civilization to follow， but not all civics and religions can be encompassed.
Once the player has formally met another civilization， they can perform diplomacy at any time. For example， if the two civilizations are on friendly terms， the player can ask to trade units and/or technology for gold and vice versa， or request opening of national borders in order to freely explore in the other civilization’s territories. The player can also use the diplomacy menu to request help in a war against a third civilization， or formally declare war on any civilization in which they engage diplomacy.
Religion plays a much more important role in Civilization IV than in the previous installments of the franchise. Impacting many of the game’s key mechanics like government civics and diplomatic relations， the game’s new religious system， according to Firaxis Games producer Barry Caudill， was added to increase gameplay depth over the entire game. The game features seven religions (Buddhism， Christianity， Confucianism， Hinduism， Islam， Judaism， and Taoism) that are founded by the first civilization to research a certain technology which varies per religion. Religions can then be spread actively through the production of missionary units or passively through means such as trade routes. Religions may be spread to domestic and foreign cities and there is no limit to the number of religions that can be present in any single city. The player may only choose one state religion at a time and all seven offer identical advantages (e.g. cities with the state religion receive bonuses in happiness， and potentially in production， science， gold and even military unit experience points).
カスタマイズ
Civilization IV is much more open to modification than its predecessors were. Game data and rules are stored in XML files， and a Software Development Kit was released in April 2006 to allow customization of game AI. The map editor supports Python.
The World Builder allows a player to either design a map from scratch or edit a preloaded template map as a starting point for a new game. The player can modify the map by placing and modifying any number of rivers， landmasses， mountains， resources， units， and cities， as well as their attributes such as Culture generation. The World Builder for Civilization IV is in-game， in contrast to previous Civilization games where the Map Editor was an external application.
More game attributes are stored in XML files， which can be edited with an external text editor or application. On September 20， 2005， Firaxis Games senior producer Barry Caudill stated that “”diting these files will allow players to tweak simple game rules and change or add content. For instance， they can add new unit or building types， change the cost of wonders， or add new civilizations. Players can also change the sounds played at certain times or edit the play list for your soundtrack.””
The Civilization IV software development kit was released on April 13， 2006， to coincide with the release of the v1.61 patch. The kit allows players to view， modify， or even completely re-write the game’s DLL source code， enabling the modification of the game’s AI and other integral parts of the game that were previously not accessible.
製造
生産・開発
The game engine for Civilization IV was built entirely from scratch， with some help from NDL’s Gamebryo engine. This decision resulted in a full 3D immersion of the game， which was the first in the series， and which allowed easier readability and smoother， more in-depth zooming capabilities. Some of the quotes relating to the technology tree and narration for the game were provided by Leonard Nimoy. The soundtrack for the game features compositions of Medieval， Renaissance， and Baroque origin， and design for the title music was influenced by The Lion King. Composer Christopher Tin wrote the opening theme song “”Baba Yetu”” (Swahili “”Our Father””)， a rendition of the Lord’s Prayer， which was performed by Stanford University’s Talisman A Cappella. The song， when rereleased， became the first piece of video game music to be nominated for and to win a Grammy Award.
改造
Sid Meier’s Civilization IV also released some bonus content， mainly to show modding capabilities:
Earth – This is the world map of the game， based on the Robinson projection of the Earth in order to optimize its size. 124×68 tiles large， it features just 9 ancient civilizations. An 18 civilizations version of this mod was later released which won the first prize at a GameFlood modding contest.
Earth Ice Age – This map is set in the world during the last ice age (20，000 years before present)， with 11 randomly picked civilizations.
Greek World – To reenact the classical Mediterranean， a special map was made， based on Hecataeus’ map of the world as it was known by the Greeks. Extra detail was also borrowed from other ancient sources such as Homer， Ptolemy， and Herodotus.
Rhye’s and Fall of Civilization – This mod changes much of the core settings of the game as an attempt at maintaining a sense of historical realism into the game. In order to do this， it introduces other features such as plagues and congresses.
Fall from Heaven – a total conversion mod that reimagines the game in a dark fantasy setting， built by Derek Paxton. Its sequel Fall from Heaven II became the most downloaded mod on CivFanatics.
文明の匿名
The game had a viral marketing campaign， revolving around a fictitious self-help organization known as Civilization Anonymous (shortened to CivAnon)， the intention being to satirise how addictive the game was. With the slogan “”No More Turns””， the premise was the following: “”Rumors have begun to circulate that the newest edition of the “”One More Turn”” franchise is on its way. STAY AWAY from this game at all costs. You will likely be powerless to its extreme addictive properties once exposed””. Various characters were created， and their scenarios were included in various trailers showing the “”inside a Civanon meeting for [Civilization] addicts
