Games with game worlds of some kind often make use of these worlds by making different parts of them have different value for gameplay. This makes it natural for players to try to have access and control to these. This [[Area Control]] may hinder other players from using the resources or other possibilities available there, or can simply be that one can oneself access them regardless if other players can do so also.

Games with a game board or game world can have the control of these as goals in their game. Besides being a goal in itself, control over areas in games can give access to otherwise unavailable actions and can make the use of actions and tactics easier.

Having implicit [[Area Control]] over the center of the game board in [[Chess]] is one of the main strategies in the game. The goal of [[Go]] is to have efficient [[Area Control]] over as much of the board using as few stones as possible. Gameplay typically begins with claiming areas in the corners, which are most easy to defend, and moves out along the sides to in the end game revolve around the center of the board.

[[Area Control]] can also be regulated through rules. For example, one of the goals in the [[Battlefield series]] is to have control over flag points. This is done by teams by having sole presences in the areas around the flags for a certain period of time. Other games, e.g. [[Risk]] and [[Greed Corp]] give players [[Area Control]] simply by entering locations (and [[Greed Corp]] lets this persist when units are moved out). [[Carolus Magnus]] and [[Imperial 2030]] let players have control over areas indirectly by controlling factions while [[Blood Bowl]] has rules making moving out of squares next to opponents risky due to the possibility of being tackled. The [[Civilization (video game) series|Civilization]], [[Hearts of Iron series|Hearts of Iron]], and the [[Europa Universalis series]] differentiate between who has [[Area Control]] over a territory and how owns it.

The design of Area Control consists of how control is achieved and what effects the control gives. Control can either be due to direct or indirect actions. Direct actions consist of reach the area itself with a Focus Loci, making it a Race to Traverse to the area. Often Contact with the area determines the winner, but the Contact may have to be an Extended Action to give Perceivable Margins and let other players try to Overcome the first claimer. Gaining Area Control due to indirect actions does not require players to have Focus Loci in the area but instead requires the use of Resources in Trading or Bidding, alternatively being given the area as an effect of Luck.

The design of [[Area Control]] in games consists of deciding how control can be achieved and what effects that control provides (which also touched upon why it is interesting to gain the control). Control can either be due to direct or indirect actions. Direct actions consist of reach areas with [[Focus Loci]] and often simple [[Connection]] with the areas determines control but the [[Connection]] may have to be an [[Extended Actions|Extended Action]] to give [[Perceivable Margins]] and let other players try to [[Overcome]] the first claimer. The use of [[Territories]] or [[Check Points]] can help make [[Area Control]] actions direct since these provide clearly identifiable targets. The construction of [[Bases]] may directly cause [[Area Control]] to be achieved. In areas already under somebody else control, [[Combat]] is typically needed when [[Area Control]] is to be achieve by direct actions (conquering cities in the [[Civilization (video game) series|Civilization]] is an example of this). Gaining [[Area Control]] by indirect actions is usually achieved by [[Negotiation]] or the use of [[Resources]] in [[Trading]] or [[Bidding]].
  
If the ownership of the area is not an Irreversible Action, the possibility of future Transfer of Controls creates Guard goals of keeping the area which are both Continuous Goals and Interferable Goals. Preventing Goals of Overcome or Eliminate can created around the Guard goal, as can Stealth when an extended sole presence is required to control the area. If the game area is larger than can be overviewed at once, the subgoal of Reconnaissance may be necessary. The Guard goal can be encouraged by giving explicit Penalties beyond any possible losses of abilities and Resources that naturally occur when the area is lost. This makes the goal of keeping the area a Committed Goal.
+
Regardless of what types of actions are needed to gain [[Area Control]], game systems can explicitly acknowledge [[Area Control]] through assigning [[Territories]]. The [[Hearts of Iron series|Hearts of Iron]] and the [[Europa Universalis series]] show how both direct and indirect actions can be used for [[Area Control]] while also making use of [[Area Control]] and [[Ownership]] of [[Territories]] as separate conditions. In these games new [[Territories]] are gained by first invading them (direct actions) and then receiving them as part of peace treaties (indirect actions). Players can only produce [[Units]] in their [[Territories]] which they have [[Area Control]] over - a player that has enemy [[Units]] in all his or her [[Territories]] cannot produce any [[Units]].
  
The common effects of Area Control is access to Producers and Resources in the area, Privileged Abilities from Controllers, providing good Game State Overview through the view from the area, or making opponents have Movement Limitations. When being in the area making completion of other goals easier, for example having positive modifiers for Combat, the action of having Area Control is a Supporting Goal.
+
Related to how [[Area Control]] is achieved is the question of whether the rules makes this control permanent or not, i.e. if gains of [[Area Control]] are [[Irreversible Events]]. [[Settlers of Catan]] lets [[Area Control]] persist until the end of the game since cities cannot be lost in this game (unless one is using ''The Cities and Knights of Catan'' [[Expansions]]) while the [[Emergent Gameplay]] of [[Go]] can make areas unconquerable even if there are no explicit rules assigning permanent control. If the ownership of the area is not an [[Irreversible Events]], the possibility of future [[Transfer of Control]] events creates [[Guard]] goals of keeping the area. While areas' [[Location-Fixed Abilities]] and [[Resource Locations]] provide natural [[Rewards]] and [[Penalties]] for gaining and losing [[Area Control]] respectively, [[Guard]] goals can be encouraged by giving additional explicit [[Penalties]] and attacks can be encouraged by giving additional explicit [[Rewards]] (e.g. the money gained by conquering cities in [[Civilization (video game) series|Civilization]]). Regardless of these issues, [[Game State Overviews]] can be considered to make players aware of who has [[Area Control]] of what.

The common reasons to try to have [[Area Control]] is because they contain [[Resources]], give access to [[Location-Fixed Abilities]] (e.g. [[Controllers]]) or [[Resource Locations]], that the areas provide good [[Line of Sight]] to other areas, or that having control makes opponents have [[Movement Limitations]] ([[Zone of Control]] extends this to nearby locations). Indirect, [[Area Control]] can help create [[Combos]] since players can position the game elements better.

Some areas naturally become focus points for [[Area Control]]. Examples of such areas include [[Choke Points]], [[Sniper Locations]], and [[Strongholds]].

[[Flanking Routes]] can be used on all these focus points to make them less easy to control, as well as provide more [[Varied Gameplay]] and likely require [[Attention Swapping]].

Having Area Control is a form of Ownership that affects the Game World. Getting Area Control over part of a Game World can be the fulfillment to Gain Ownership goals defined by Goal Points, and make the areas into Strategic Locations. Besides the Rewards of completing the goal, areas may be Strategic Locations due to the Game State Overview the areas gives or the presence of Producers, Controllers or Resources. Like other cases of ownership, having Area Control can give Emotional Immersion and modulates how players perceive potential losses of areas.

Having [[Area Control]] is a form of [[Ownership]] that affects [[Game Worlds]]. When this [[Ownership]] can be contested, [[Area Control]] easily leads to [[Emotional Engrossment]] and [[Conflicts]] over [[Gain Ownership]] goals. It specifically affects places with [[Location-Fixed Abilities]] since they can provide players with [[Privileged Abilities]] (if they are scarce) and these [[Abilities]] can be [[Temporary Abilities]] if [[Ownership]] can change. If achieved [[Area Control]] cannot be contested, this creates [[Entrenching Gameplay]]. [[Area Control]] can be used to create [[Expansion]] phases by placing it in focus on gameplay.

Being in control over who can move within an area in the game world, or having access to actions linked to locations in the game world.

Games with game worlds of some kind often make use of these worlds by making different parts of them have different value for gameplay. This makes it natural for players to try to have access and control to these. This Area Control may hinder other players from using the resources or other possibilities available there, or can simply be that one can oneself access them regardless if other players can do so also.

Examples

Having implicit Area Control over the center of the game board in Chess is one of the main strategies in the game. The goal of Go is to have efficient Area Control over as much of the board using as few stones as possible. Gameplay typically begins with claiming areas in the corners, which are most easy to defend, and moves out along the sides to in the end game revolve around the center of the board.

Having Area Control over the places where new weapons and power-ups appear is vital in multiplayer matches in First-Person Shooters such as the Quake series and Unreal Tournament series.

Area Control can also be regulated through rules. For example, one of the goals in the Battlefield series is to have control over flag points. This is done by teams by having sole presences in the areas around the flags for a certain period of time. Other games, e.g. Risk and Greed Corp give players Area Control simply by entering locations (and Greed Corp lets this persist when units are moved out). Carolus Magnus and Imperial 2030 let players have control over areas indirectly by controlling factions while Blood Bowl has rules making moving out of squares next to opponents risky due to the possibility of being tackled. The Civilization, Hearts of Iron, and the Europa Universalis series differentiate between who has Area Control over a territory and how owns it.

Area Control can be shared between players. One example of this can be found in the Settlers of Catan where all players that have settlements bordering a hex can gain resources from it.

Using the pattern

The design of Area Control in games consists of deciding how control can be achieved and what effects that control provides (which also touched upon why it is interesting to gain the control). Control can either be due to direct or indirect actions. Direct actions consist of reach areas with Focus Loci and often simple Connection with the areas determines control but the Connection may have to be an Extended Action to give Perceivable Margins and let other players try to Overcome the first claimer. The use of Territories or Check Points can help make Area Control actions direct since these provide clearly identifiable targets. The construction of Bases may directly cause Area Control to be achieved. In areas already under somebody else control, Combat is typically needed when Area Control is to be achieve by direct actions (conquering cities in the Civilization is an example of this). Gaining Area Control by indirect actions is usually achieved by Negotiation or the use of Resources in Trading or Bidding.

Regardless of what types of actions are needed to gain Area Control, game systems can explicitly acknowledge Area Control through assigning Territories. The Hearts of Iron and the Europa Universalis series show how both direct and indirect actions can be used for Area Control while also making use of Area Control and Ownership of Territories as separate conditions. In these games new Territories are gained by first invading them (direct actions) and then receiving them as part of peace treaties (indirect actions). Players can only produce Units in their Territories which they have Area Control over - a player that has enemy Units in all his or her Territories cannot produce any Units.

Related to how Area Control is achieved is the question of whether the rules makes this control permanent or not, i.e. if gains of Area Control are Irreversible Events. Settlers of Catan lets Area Control persist until the end of the game since cities cannot be lost in this game (unless one is using The Cities and Knights of Catan Expansions) while the Emergent Gameplay of Go can make areas unconquerable even if there are no explicit rules assigning permanent control. If the ownership of the area is not an Irreversible Events, the possibility of future Transfer of Control events creates Guard goals of keeping the area. While areas' Location-Fixed Abilities and Resource Locations provide natural Rewards and Penalties for gaining and losing Area Control respectively, Guard goals can be encouraged by giving additional explicit Penalties and attacks can be encouraged by giving additional explicit Rewards (e.g. the money gained by conquering cities in Civilization). Regardless of these issues, Game State Overviews can be considered to make players aware of who has Area Control of what.

The common reasons to try to have Area Control is because they contain Resources, give access to Location-Fixed Abilities (e.g. Controllers) or Resource Locations, that the areas provide good Line of Sight to other areas, or that having control makes opponents have Movement Limitations (Zone of Control extends this to nearby locations). Indirect, Area Control can help create Combos since players can position the game elements better.

Some areas naturally become focus points for Area Control. Examples of such areas include Choke Points, Sniper Locations, and Strongholds. Arenas can also work but then because of their relation to the previously mentioned patterns or because they contain Check Points. Flanking Routes can be used on all these focus points to make them less easy to control, as well as provide more Varied Gameplay and likely require Attention Swapping. The possibility to have Strategic Knowledge about such locations, e.g. because they are fixed features in maps which are reused, are likely to affect how players strive to have Area Control.

Interface Aspects

Area Control is typically not shown in game interfaces unless it is formalized with Territories.

Consequences

Having Area Control is a form of Ownership that affects Game Worlds. When this Ownership can be contested, Area Control easily leads to Emotional Engrossment and Conflicts over Gain Ownership goals. It specifically affects places with Location-Fixed Abilities since they can provide players with Privileged Abilities (if they are scarce) and these Abilities can be Temporary Abilities if Ownership can change. If achieved Area Control cannot be contested, this creates Entrenching Gameplay. Area Control can be used to create Expansion phases by placing it in focus on gameplay.

Area Control easily spawns different types of goals for players. Reaching the areas that one wishes to control creates Traverse goals, and when several players are trying to reach the same area this becomes Races. If the areas is already under somebody else control, wanting to take that area creates Overcome goals. Stealth can occur when an extended sole presence is required to control an area; this can be a successful tactic in multiplayer games such as Battlefield 2. In many cases trying to gain Area Control are Supporting Goals to other goals; this is maybe most explicit when Area Control can help create Combos.

When many areas exist that can be controlled, knowing the values of each of these is a form of Strategic Knowledge. Choosing which of these to try and control is an example of having a Selectable Set of Goals which require players to do Risk/Reward choices or Trade-Offs. Maintaining Area Control is a Continuous Goal and Interferable Goal to Guard a location; maintaining control over several areas changes this to Reconnaissance goals or requires Attention Swapping - in games with Teams this can be reduced back to Guard goals if Cooperation works.
