A video game, also known as a computer game or just a game, is an electronic game that involves interaction with a user interface or input device to generate visual feedback from a display device, most commonly shown in a video format on a television set, computer monitor, flat-panel display or touchscreen on handheld devices, or a virtual reality headset. Most modern video games are audiovisual, with audio complement delivered through speakers or headphones, and sometimes also with other types of sensory feedback. Some video games also allow microphone and webcam inputs for in-game chatting and livestreaming.
A massively multiplayer online role-playing game (MMORPG) is a video game that combines aspects of a role-playing video game and a massively multiplayer online game.
Roguelike is a style of role-playing game traditionally characterized by a dungeon crawl through procedurally generated levels, turn-based gameplay, grid-based movement, and permanent death of the player character. Most roguelikes are based on a high fantasy narrative, reflecting the influence of tabletop role-playing games such as Dungeons & Dragons.
A game engine is a software framework primarily designed for the development of video games and generally includes relevant libraries and support programs such as a level editor. The "engine" terminology is akin to the term "software engine" used more widely in the software industry.
A game programmer is a software engineer, programmer, or computer scientist who primarily develops codebases for video games or related software, such as game development tools. Game programming has many specialized disciplines, all of which fall under the umbrella term of "game programmer". A game programmer should not be confused with a game designer, who works on game design.
Game balance is a branch of game design with the intention of improving gameplay and user experience by balancing difficulty and fairness. Game balance consists of adjusting rewards, challenges, and/or elements of a game to create the intended player experience.
In video games, artificial intelligence (AI) is used to generate responsive, adaptive or intelligent behaviors primarily in non-playable characters (NPCs) similar to human-like intelligence. Artificial intelligence has been an integral part of video games since their inception in 1948, first seen in the game Nim. AI in video games is a distinct subfield and differs from academic AI. It serves to improve the game-player experience rather than machine learning or decision making. During the golden age of arcade video games the idea of AI opponents was largely popularized in the form of graduated difficulty levels, distinct movement patterns, and in-game events dependent on the player's input. Modern games often implement existing techniques such as pathfinding and decision trees to guide the actions of NPCs. AI is often used in mechanisms which are not immediately visible to the user, such as data mining and procedural-content generation. One of the most infamous examples of this NPC technology and gradual difficulty levels can be found in the game Mike Tyson's Punch-Out!! (1987).
In massively multiplayer online games, an instance is a special area, typically a dungeon, that generates a new copy of the location for each group, or for a certain number of players, that enters the area. Instancing, the general term for the use of this technique, addresses several problems encountered by players in the shared spaces of virtual worlds. It is not widely known when instances were first used in this genre. However, The Realm Online (1996) is sometimes credited as introducing the concept.
In video games, a level is any space available to the player during the course of completion of an objective. Video game levels generally have progressively increasing difficulty to appeal to players with different skill levels. Each level may present new concepts and challenges to keep a player's interest high.
In computing, procedural generation is a method of creating data algorithmically as opposed to manually, typically through a combination of human-generated content and algorithms coupled with computer-generated randomness and processing power. In computer graphics, it is commonly used to create textures and 3D models. In video games, it is used to automatically create large amounts of content in a game. Depending on the implementation, advantages of procedural generation can include smaller file sizes, larger amounts of content, and randomness for less predictable gameplay.
The Corrupted Blood incident took place between September 13 and October 8, 2005, in World of Warcraft, a massively multiplayer online role-playing game (MMORPG) developed by Blizzard Entertainment. When participating in a certain boss battle at the end of a raid, player characters would become infected with a debuff that was transmitted between characters in close proximity. While developers intended to keep the effects of the debuff within this boss's game region, a programming oversight soon led to an in-game pandemic throughout the fictional world of Azeroth.
Game testing, also called quality assurance (QA) testing within the video game industry, is a software testing process for quality control of video games. The primary function of game testing is the discovery and documentation of software defects. Interactive entertainment software testing is a highly technical field requiring computing expertise, analytic competence, critical evaluation skills, and endurance. In recent years the field of game testing has come under fire for being extremely strenuous and unrewarding, both financially and emotionally.
Cheating in video games involves a video game player using various methods to create an advantage beyond normal gameplay, usually in order to make the game easier. Cheats may be activated from within the game itself, or created by third-party software or hardware. They can also be realized by exploiting software bugs; this may or may not be considered cheating based on whether the bug is considered common knowledge.
Dynamic game difficulty balancing (DGDB), also known as dynamic difficulty adjustment (DDA), adaptive difficulty or dynamic game balancing (DGB), is the process of automatically changing parameters, scenarios, and behaviors in a video game in real-time, based on the player's ability, in order to avoid making the player bored or frustrated. The goal of dynamic difficulty balancing is to keep the user interested from the beginning to the end, providing a good level of challenge.
Since their inception in the 1970s, video games have often been criticized by some for violent content. Politicians, parents, and other activists have claimed that violence in video games can be tied to violent behavior, particularly in children, and have sought ways to regulate the sale of video games. Studies have shown no connection between video games and violent behavior. The American Psychological Association states that while there is a well-established link between violent video games and aggressive behaviors, attributing acts of violence to violent video gaming "is not scientifically sound."
Since the origin of video games in the early 1970s, the video game industry, the players, and surrounding culture have spawned a wide range of technical and slang terms.
Chartboost is a San Francisco-based mobile game in-app programmatic advertising and monetization platform. Chartboost SDK enables developers to monetize on their mobile apps and connect advertisers to global in-app inventory. Chartboost's platform allows video game developers to create customized interstitial and video ads to promote new games. Developers have direct access to game data derived from Chartboost-enabled games. As of 2016, Chartboost had been integrated into more than 300,000 games with 40 billion game sessions per month.
Felgo is a cross-platform development tool, based on the Qt framework. It can be used to create mobile apps or games. Felgo apps and games are supported on iOS, Android, Windows Phone, embedded devices and desktop devices. Felgo developers use QML, JavaScript and C++ to create mobile apps and games.
A gacha game is a video game that implements the gachapon machine style mechanics. Similar to loot boxes, gacha games entice players to spend in-game currency to receive a random in-game item. Some in-game currency generally can be gained through game play, and some by purchasing it from the game publisher using real-world funds.
GDevelop is a 2D and 3D cross-platform, free and open-source game engine, which mainly focuses on creating PC and mobile games, as well as HTML5 games playable in the browser. Created by Florian Rival, a software engineer at Google, GDevelop is mainly aimed at non-programmers and game developers of all skillsets, employing event based visual programming similar to engines like Construct, Stencyl, and Tynker.
