Game balance is a branch of game design that is described as a mathematical-algorithmic model of a game's numbers, game mechanics, and relations between the two. Game balance consists of adjusting values to create a certain user experience. Players’ perception and experience are the objectives of game balancing. Overview and development Similar to game design, the definition of game balance is different between various game designers and developers. Game balance is present in every type of game in some form, so there are no existing comparable interpretations of the concept. Even so, game balance is generally understood as introducing a level of fairness for the players. This includes adjusting difficulty, win-loss conditions, game states, economy balancing, and so on to work in tandem with each other. The concept of game balance depends entirely on the type of game being discussed. Most game designers agree that game balancing serves towards providing an engaging player experience, especially through metagame. Game balance is and continues to be heavily discussed among game design veterans, some of whom include Ernest Adams, Jeannie Novak, Ian Schreiber, David Sirlin, and Jesse Schell. The topic is also featured in many YouTube channels specializing in game design topics, including Extra Credits, GMTK and Adam Millard. Terms specific to game balance PvP, PvE and Co-Op Games PvP is an acronym for player versus player and describes games that feature a direct competition between human players, while PvE is an acronym for player versus environment. In games featuring PvE, players engage themselves against other computer-controlled non-player characters (NPCs). Co-op is short for "cooperative" and refers to PvE games in which multiple players face NPCs. This does not necessarily exclude some possibilities for PvP, wherein players must engage against both CPU opponents as well as player opponents simultaneously. Game elements These are elements that appear within a video game that contributes to the overall gameplay experience. In most game design frameworks, game elements are generally categorized into separate groups of elements to help describe their roles in the games. A game element can refer to anything, ranging from a special ability the player can use to the systemic relations between different game mechanics in a game. Game mechanics Game mechanics are game constructs with which the player interacts with the game world. They define the goal, how players can achieve and how they cannot, and what happens when they try. These would
