For games where players play against opponents, the players need to feel that they can affect the outcome of the game. If a game is designed with a certain game time or amount of gameplay, and players feel powerless, these players have to two possibilities: endure gameplay that is uninspiring or suffer that gameplay breakdown due to the players desire to stop playing. To avoid these situations, games can have Balancing Effects built into them so that all players are more likely to feel that they have a chance to win over their opponents until the intended conclusion of the competition.
Example: Power-ups in Monkey Race 2 in Super Monkey Ball 2 give speed boosters only to the players that are not leading the races. Further balancing effects can be added by players through the option that makes the leader have a lower maximum speed than the other players.
Example: multiplayer online first-person shooters often have possibilities to force teams to be balanced in numbers. Some, such as Return to Castle Wolfenstein: Enemy Territory, have functionality that can automatically reassign teams based on experience to try and balance the teams further.
Balancing Effects can be designed in a game to be preemptive or correcting. Preemptive Balancing Effects try to maintain Player Balance so that imbalances do not occur, while correcting Balancing Effects try to correct imbalances when they have occurred. An alternative to Balancing Effects, which can be used together with them, is Limited Foresight. This also gives players a Perceived Chance to Succeed but in this case, it may only be an Illusion of Influence.
Handicaps are preemptive Balancing Effects that are put into effect before gameplay begins. Making Extended Actions into Interruptible Actions is a form of preemptive Balancing Effect as other players can interfere with the actions, especially if they do not have any effect before they are completed. Delayed Effects in general have a certain Balancing Effect, as they give players the possibility to prepare for the effects. Other ways of creating preemptive Balancing Effects consist of designing Illusionary Rewards, requiring Tradeoffs, allowing players to choose Selectable Sets of Goals that best fit their abilities, or providing Diminishing Return to players that otherwise could become clear leaders. If the effects are direct, these effects can ruin the Illusion of Influence for players and even make them avoid trying to achieve what should be goals for them. Having Balancing Effects affect the players indirectly can solve this, for example through Character Development or making New Abilities additions to those already used with Budgeted Action Points.
Examples of correcting Balancing Effects include giving New Abilities or Improved Abilities to disadvantaged players and giving Ability Losses or Decreased Abilities to advantaged players. The classic case used in Races is a Decreased Ability in the form of Movement Limitation giving a lower maximum speed. To avoid players losing Illusion of Influences, the positive effects are usually Rewards to the disadvantaged players for completing goals, while the negative effects are usually Penalties to the advantaged players for failing goals. The evaluation function that determines the Balancing Effects is for the same reason often hidden from players, for example, by making all Pick-Ups look the same though they have different effects, or by hiding the actual rolling of Dice to be able to fudge the results. Another example of a correcting is to decide the order of Turn Taking so that disadvantaged players give the most advantageous positions.
Transfer of Control can also be used to correct imbalances, but these are often linked to the Rewards or Penalties of any of the players. A common solution is to have forced Shared Rewards, so that the player who gains the Reward must share it with someone else, typically the most disadvantaged player. Controlling how Spawning occurs can also be corrective, either placing disadvantaged players at Strategic Locations or placing advantaged players at bad locations.
Games with more than two teams or players competing against each other automatically have some corrective Balancing Effects. Players in these games perceived as leading may be the starting point of Mutual Goals for Uncommitted Alliances, which have the intentions of ganging up against the leader. This is common in games with King of the Hill goals but can also be found in games that allow Player Decided Results and Player-Decided Distribution of Rewards & Penalties. Sufficient Game State Overviews, for example, public Scores, so players can notice leaders, are required for this form of Balancing Effect to occur.
Game Masters, as Dedicated Game Facilitators that have constant access to the complete game state and can enforce their own Player Decided Results, can perform both preemptive and corrective balancing effects during gameplay.
Games using primarily Randomness to judge outcomes can easily be designed to have Balancing Effects over time or when considering several game sessions together. However, games with Dedicated Game Facilitators can fake the Randomness, for example, the results of Dice rolls, to explicitly create Balancing Effects during gameplay.
The presence of Balancing Effects strengthens or prolongs players' Perceived Chance to Succeed but lessens the Perceivable Margins of the game and removes feelings of Game Mastery in the game. Balancing Effects often provide the Right Level of Difficulty and Smooth Learning Curves in games by making challenges sufficiently difficult.
Balancing Effects are used in Multiplayer Games to avoid too large differences of Asymmetric Abilities between players. They can achieve Player Balance or Team Balance during gameplay, often to maintain Tension as long as possible in the game and to allow Higher-Level Closures as Gameplay Progresses.
