Video games or software which are still protected under copyright, but are no longer sold by the copyright holder. Gamers typically don't have an ethical problem pirating abandonware since, as they claim, the copyright holders won't lose money since they aren't trying to sell the title anyway. "Abandonware" is not a legal term, and still constitutes as breaking the law.

AC adapter

A power adapter typically used to plug in otherwise battery powered devices. Prior to long-life rechargeable batteries, AC adapters were sold for most portable video game platforms.

Short for aggravation. An amount of hostile attention from an enemy or other player. AI-controlled enemies are typically programmed to attack the player who cause them the most aggro.

agile development model

A game development model where less emphasis is placed on planning out exactly what the game will be like. Instead, developers frequently design and play test demos in an attempt to find what works and use feedback from the testers to guide the game's progress. Developers usually prefer this method because it makes it much easier to change game play elements that don't appear to be working, but publishers rarely like this model because it's much more difficult to figure out where in a game's development cycle in order to plan for advertising and distribution. The agile development model is contrasted with the waterfall development model.


See "artificial intelligence."

AI vs. AI

When an AI faces off against another AI. Some games allow this as a feature, particularly sports games which allow you to serve as "coach" for the AI. Other games use this as the basis of their game play and expect players to program their own AIs to battle each other.

attract mode

A special mode in a game used to entice people into playing the game. Attract modes were created for arcade games as a way to attract potential players by showing demos of game play, often focusing on the more technologically advanced aspects of the game. Attract modes also usually showed the game's title screen, high score list, and some backstory, while also serving as a screen saver. Although console games don't really need an attract mode, many game designers included them to make the game feel more like an arcade release. The home line of Atari 8-bit platforms would include an attract mode which cycled colors in order to prevent burn-in.

auto scrolling

When the map scrolls on its own outside of the player's control.

automatic transmission

In games which feature driving, a transmission that automatically shifts gears for the player, as opposed to a manual transmission.


When the game automatically saves your progress without you needing to do so. Designers usually have the game autosave before a significant event.


A representation of the player inside the game. Similar to a character, but an avatar is typically meant to refer to the player herself, not a different character.



Often abbreviated to BOB or BOTB. Refers to what is printed on the back of a boxed game. Without any other knowledge of the game, potential buyers used what was printed on the back of the box to gauge the quality of the game, and, as such, box designers used them for advertising. The text often over-sold the game, and the impressive screenshots were often from better ports or cut scenes, not the typical game play.


A copy of video game media (diskette, CD-ROM, etc.) or the process of making a copy, to ensure the original is kept safe. Some nations allow for the owner of any software to make and use a single backup provided it is not shared with anyone else. Also refers to backing up files generated by a game (save states, configuration files, etc.)

bad ending

A ending sequence of a game which doesn't present a positive outcome, as opposed to a good ending.

ball and paddle

A genre of video game where the player controls a paddle which must hit a ball.

beat 'em up

A genre of video game where the player controls a character who beats up other characters. Also called a "brawler" or, when the characters wield weapons, a "hack-and-slash."

beginner trap

Something that results in a bad outcome with no way to know it's bad until you fall for it. As the name suggests, it's a trap for beginners; only after being burned by it, the player will know to avoid it. An example of "fake difficulty."


A stage in game development where all the principle work is done, but it still needs to be tested for bugs and balance issues. Promotional advertising ramps up at this point.

Short for bit block transfer. Describes quickly moving data in memory from one location to another, and is typically used to move bitmapped graphics from a buffer to the screen or another buffer. Masking usually takes place at this time.


A mapping of information to bits. In video games, this is typically the mapping of pixels to bits in order to store graphics.

black and white

See monochrome.

blast processing

boot (process)

The process of starting a device. The boot process can be divided into a cold boot or warm boot. A cold boot occurs when the device first receives power and must begin fresh. A warm boot refers to having a device which already has power to perform most of the same processes, but often skips some of them.


A particularly difficult enemy who guards the end of a stage or a section in a game.

boss rush

A type of character in a game that relies heavily on hand-to-hand combat.

brawler (genre)

See beat 'em up.

big box

Describes early video game boxes which were frequently much larger than those from the 2000s when computer game companies began shipping them in smaller boxes similar to the size of console games. The larger boxes were often mostly empty space, but occasionally necessary to fit larger manuals, maps, posters, and trinkets.


Something which increases the power of a character. An example would be a potion of strength which temporarily increases a character's strength.

buffer overflow

When data is written to an area of memory that cannot hold it resulting in a bug.


A coding oversight the results in behavior undesired by the developers. Also called an error or glitch.

bullet hell

A sub-genre of shooter where the player is expected to avoid a large number of enemy projectiles.


The process in which a television or monitor is damaged by showing the same high-intensity display for a prolonged period of time. The term "burn-in" is used because the image will still be seen even after it's no longer displayed, as though it has been burned into the screen. Burn-in was common on older CRTs, RPTV, as well as plasma and OLED displays, but not as common in LCD displays. Early video games, like those developed for the Atari, had special modes to cycle through colors in order to prevent burn-in.


A unit of information which is made up of several bits. In the early days of computing, bytes were made up from various numbers of bit, but most manufacturers have settled on eight (also known as an octet). When in a byte, bits are usually not meant to be interpreted as individual pieces of information, but combined to form a value from 0-255. What this value is dependent on how it is meant to be interpreted.



A process used to ensure the accuracy of control devices by comparing the current value to a know standard. Primary used for analog joysticks and touch pads.

camera screw

When a poorly programmed camera causes the player to mess up. Especially common in early 3D games, and a form of "fake difficulty."

campaign mode

See "story mode."


Remaining at a certain area in a game. In versus mode, camping is typically done to protect an area from attackers, rack up a high number of frags by having a clear view of a high traffic area (especially a spawn point), or waiting until other players injure each other and then finishing them off. Camping is often looked down upon and some games punish campers by revealing their location to all other players. When not in versus mode, camping is usually referred to as "grinding" or "farming."


Aspects of a game that are part of the official story, as opposed to non-canon.

capture the flag

A form of multiplayer where teams try to capture an object, often a flag, that is located in the opposing team's base and bring it to their own base. Based on the traditional game. Often abbreviated to CTF.


Players who do more work on a team than others are said to "carry" the less useful members. Players who are being carried are looked down upon by those who are carrying them, and may be booted from the team. See also "twinking."


See "ROM cartridge."

cartridge port

A connector where a ROM cartridge can be plugged in. Common on 8 and 16-bit video game platforms.

cartridge tilting

Deliberately interfering with the connections of a ROM cartridge, often by tilting one side so the contacts aren't fully connected, in order to cause glitches in the game. Tilting the cartridge too much will cause the game to crash or the console to reboot, but just enough will corrupt small portions of the game in a way similar to a corrupter. Cartridge tilting is done to add a twist to existing game play.


An protective covering or carrying device for a, usually portable, game console. Cases are usually made out of plastic, rubber, or silicone.


See cassette tape.

cassette tape

A double-sided magnetic tape housed in a plastic shell with two reels. Data can be stored on it or read from it with a tape recorder. It was a popular media for storing video games, especially in the Japanese and European markets during the 1980s. It was made obsolete by the 3.5" floppy disk.

casual game

A genre of video game that can be easily picked up and played at a leisurely pace without much commitment. The game play usually has very shallow learning curve and limited controls or possible actions. Casual games typically auto-save the player's progress and can be ended at any time without negative consequences and are usually designed for portable gaming platforms or web browsers so they can be played at any time.

Cat 5

Short for Category 5, a type of twisted pair cable used for networking video game platforms together through Ethernet. Usually uses RJ45 connectors.

cathode-ray tube

The older "tube" style of television or monitor which uses an electron emitter to excite phosphors painted on the back side of the tube. Most games developed in the first six video game generations were designed under the assumption the player would be using a CRT.


An optical disc capable of storing data which can be read from it with a laser. The data is formatted according to the Yellow Book standard. It was used as the primary video game media of home computers from the 1990s to 2000s as well as several video game consoles. Replaced by the DVD-ROM.


Short for Computer Entertainment Rating Organization, a video game content rating system used by Japan for video game consoles.


Short for Color Graphics Adapter, a display technology developed by IBM to give color display to IBM Personal Computers.

challenge mode

A common game style where the player is expected to play the existing game but with additional challenges like less time, fewer items, strong opponents, and the like. Often synonymous with "hard mode."

channel selector

For platforms that connect to a television through RF output, a switch which lets the user decide which channel on their television the video game signal would be sent to. Common channels for NTSC platforms were 2, 3, and 4. This is sometimes labeled "high and low," and sometimes and analog dial instead of a switch.

chaotic cooperation

In cooperative games, this refers to players who are trying to achieve the same goal, but haven't developed or practiced strategies together, so they aren't as effective at it. This is contrasted with "symphonic cooperation."


A representation of a character inside a game. Similar to an avatar, but a character is meant to represent someone other than the player. If the player can control the character, it is a "playable character," otherwise it is a "non-playable character."

character creation

The process of creating a new character and deciding its attributes. This typically includes the character's appearance, but might also include other attributes like race, class, stats, skills, etc. This is common in character-centric genres like role-playing games.

charged shot

In shooters, a weapon that allows the player to charge up their weapon in order to shoot a projectile that is more powerful than normal.


An attribute for a character or unit which typically affects how well they interact with other characters or units.


The process of exploiting a game by subverting its rules. Also, a piece of software or hardware that allows a player to cheat, or a person who cheats.

cheating artificial intelligence

When the AI-controlled opponent doesn't have to abide by the same rules as the player.

checkpoint (navigation)

A location on a map that a player is expected to reach, typically as part of a mission.

checkpoint (racing)

The next location the player must reach before time runs out.


Repeatedly using a tactic in a game, especially one which doesn't require much skill or is overpowered, especially in fighting games. For example, repeatedly using Ryu's hadoken in Street Fighter II: The World Warrior. Cheesing is not the same as cheating, as it falls within the allowed rules of the game, but it is still generally frowned upon because it's annoying to the player on the receiving end and it doesn't result in interesting game play. However, cheesing remained commonplace in any game where it's effective, which is an indication that a game isn't properly balanced.

chiclet keyboard

A keyboard which uses a single flexible sheet over a membrane keyboard to give the keys some tactile feedback. Typically associated with lower quality computers in the 1980s. The name is derived from the fact that the keys look similar to Chiclet brand chewing gum.


See "cut scene."


A specific type or category of character which has attributes or abilities befitting it. There are classes common to specific settings, for example knights and wizards in fantasy settings, medics and soldiers in military settings, etc. Classes are typically used in role-playing games, but also show up in various other character-centric genres.


Computer platforms that connect to a server.


The prevention of an entity from going through something which is solid. Also bypassing the process.

code wheel

A wheel-shaped device similar to a decoder ring and used as copy protection. They were typically printed on paper or cardboard and contained many different codes. Most of the codes would be obscured by the wheel, and only a handful would be visible through cut out windows. To operate them, a game would tell the player to turn the wheel to a specific position, then read the code visible in a particular window. These shapes were chosen because they required more effort to duplicate than other methods.

coin door

A locking door at the front of an arcade machine which gives access to the coins. Often the same as the service door which houses the coin slots and coin return chutes.


When two entities in a video game collide, that it, occupy an overlapping area in game space.

collision box

The area around a video game object which is capable of colliding with something else. Collision boxes often do not match the shape of the shape of the entity they are applied to. In early video games this was almost always a box due to hardware restrictions, but later games employed circles, complex polygons, and, in the move to 3D, 3D polygons.

collision detection

The process by determining when two game entities collide. Many different methods have been devised over time, each with different benefits and shortcomings. Poorly designed collision detection causes game entities to exhibit undesired behavior like walking through or getting stuck in solid objects, falling through the floor, taking hits when they aren't visually near another entity, etc.

color cycling

Shifting the colors in a palette. Early 8 and 16-bit games often used color cycling to create the illusion of animation without having to draw different graphics.


Short for combination, a set of actions in a series. Common in fighting and rhythm genres.


A genre of video game which incorporates humor, satire, jokes, and various other comedic elements.


Anything related to the Commodore company or the hardware they produced. In the early 1980s, Commodore was one of the primary developers of the home computer. Their Commodore 64 remains the best-selling single computer model in the USA.


A gamer who tries to complete every aspect of a game 100%. For example, unlocking all hidden content, getting every achievement, seeing every ending, etc.

component video

An analog signal format which separates the video signal into three channels which results in a clearer picture than composite. It usually uses cables with RCA connectors. Many 16 and 32-bit video game platforms used this for video output. Although the plugs are colored red, green, and blue, only a digital signal uses RGB, an analog signal uses YCbCr, but still has RGB plugs.

composite video

An older analog signal format for NTSC, PAL, or SECAM video using a cable with an RCA connector. As the name suggests, everything aspect of the video signal is merged together in a composite signal. Many 8 and 16-bit video game platforms used this for video output.


A home video game platform designed primarily to play video games. This differs from a portable video game platform, or a home computer. The term "console" typically refers to the primary unit of a home video game system where the bulk of the hardware is housed.

console generation

How home video game consoles are grouped throughout history. The criteria is quite arbitrary and is typically based on release by the best-selling hardware. Typically, each subsequent generation is more powerful than the previous.

console war

Refers to aggressive marketing campaigns between the more popular video game consoles. Popular console wars included Nintendo and Sega in the 1980s and 1990s and Sony and Microsoft in the 2000s.


A character or unit attribute which typically affects how hard they are to hurt or kill. Often correlated with energy and life units.

content rating

A grouping system handled by a governing body designed to inform parents of possible objectionable content in a game. Examples include the ESRB, PEGI, IARC, etc. Despite their intentions, content ratings invariably lead to censorship.


After getting a game over, the act of returning to the game while maintaining some or all of your progress. Arcade games require the player to purchase an additional credit to continue, while games made for the home market usually offer a limited number of continues.

control panel

On an arcade cabinet, it's the surface where the controls (e.g., joysticks and buttons) are mounted.


Any input device used to control an aspect of a video game. Examples include a joystick, gamepad, keyboard, mouse, flight yoke, pressure sensitive mat, etc.

conversion kit

A collection of arcade hardware and materials necessary to convert an existing arcade cabinet into a different game, typically at a much lower cost than buying the new cabinet outright.

cool down

The length of time a player must wait until the next time they can do something. Cool downs are often applied to special moves in order to prevent the player from spamming them.


See "cooperative."


A form of multiplayer where the players work together for a common goal.

copy protection

A deliberately misleading term for "copy prevention."

copy prevention

Any of the many methods game developers use to try and prevent people from making illegal copies of their games. Some of these methods include requiring the player to type a specific word from the manual, code wheels, writing the data to media in an uncommon way which prevented them from being easily copied, and so forth.


A device used to purposely corrupt an area of memory where a video game is stored. This is used during the reverse engineering process to help map where specific areas of the game's data are stored by observing what is changed after the area is corrupted. For example, if you corrupt an area of the the game's memory, and it changes the appearance of the character sprite, you can assume that area you corrupted contains the character's bitmap graphics. The Game Genie is a popular hardware-based corrupter, but modern emulators now feature software corrupters.

cover art

Refers to the art on the cover of a game box or case. Early video games were notorious for having gorgeous cover art that looked far more impressive than the game itself.

cover shooter

A sub-genre of the shooter where the player has their maneuver their character behind various forms of protective cover while shooting back at their opponents.

CPU (hardware)

Short for central processing unit. The part of a circuit board which performs the bulk of the processing. CPUs usually take the shape of integrated circuit microprocessors.

See "AI vs. AI."


A modified version of a video game where copy protection or DRM has been bypassed, or the process of making a crack.


A person or group of people who crack video games.


Building something in a game from constituent parts. Many games include crafting minigames, especially sandbox games.

credit (unit)

The cost of a single play for an arcade-style game. Usually, paying for one credit will buy the player multiple lives (or attempts). For many years a credit was synonymous with a quarter, but inflation increased the cost of play, so games would charge more than $0.25 for a credit. Many arcade games let you purchase additional credits before and during game play. If the game supports it, buying a credit after a game over lets you continue where you left off. Although the term originated with pay-to-play arcade games, it was carried over into many home games as well.


A cut scene which displays the names of the game's production staff. Typically displayed at the ending of game, or, sometimes the beginning, just like with films. Also called a staff roll.


A special type of attack which does more damage than normal. Typically occurs randomly, though the game may include ways to increase their likelihood. Can also refer to a condition where a character is extremely close to death. Often shortened to "crit."

cross genre

See multi-genre.


A game which combines the characters or settings of two established franchises. For example, Capcom vs. SNK: Millennium Fight 2000 is a fighting game which includes characters from several franchises owned by either company.


See cathode-ray tube.


The time during game development when developers work overtime to try to finish the game before the deadline. This usually occurs late in development as the deadline draw near and is a symptom of unreasonable deadlines, poor management, or both.


See "capture the flag."

cut scene

A narrative scene outside of the player's control. If the player has some control, it's a quick time event.

cute'em up

A sub-genre of shooter which incorporates cute graphics. A portmanteau of "cute" and "shoot 'em up."



Short for "directional pad," a flat control device with multiple directions which is slightly raised to allows the user to press the D-pad in different directions. The most popular configuration is a 4-way game pad with directions for up, down, left, and right, mounted on a rocker which allows two neighboring directions to be pressed at the same time, but prevents opposite directions from being pressed at the same time.


A family of connectors used in a wide variety of video game platforms.


A 2-row, 15-pin D-subminiature connector used on IBM-compatible home computers for connecting joysticks. This caused it to frequently be referred to as a "game port." IT was also used on several video game consoles as an expansion port including the Famicom, Atari 5200, Jaguar, and others.

damage boost

See "rocket jump."

damage sponge

Something which takes an obscene number of hits to defeat.

damsel in distress

A common trope where a woman, often a princess, needs rescuing, usually by a man.


A common control mechanic where a player can cause their character to move at an accelerated rate for a short time. When moving in reverse, this is usually called a back-dash. When moving forward, this is commonly an offensive technique, but, when moving backward, it's commonly a defensive technique. It has similarities with a "slide."

dating simulation

A genre of video game which attempt to simulate romantic dating. They often use erotic imagery.


A 2-row, 9-pin D-subminiature connector used on a number of 8 and 16-bit video game platforms for connecting controllers including the Atari 2600, Commodore 64, Amiga, Master System, Genesis, and more, as well as used by many home computer models for peripherals.


A 3-row, 15-pin D-subminiature connector most commonly recognized as the VGA connector.

switch box

A mechanism which can switch between two or more different forms of input. In video games, a switch box changes between the signal from a video game platform and a television antenna. Most switch boxes were also RF adapters. Early video games connected to a television by sending an RF signal to a television's antenna input, but this prevents the user from being able to watch television without first disconnecting the video game and reconnecting the antenna. To prevent this, video game manufacturers used a switch box which would have both the video game and antenna connected to it, and the user can switch between either input. The first versions of the switch box required the user to manually switch between them, but later models would use the antenna by default, but switch over to the video game when the console was turned on. After televisions began including standardized input like composite and component, the consoles stopped shipping with switch boxes.

symphonic cooperation

In cooperative games, symphonic cooperation refers to players who work well together to achieve a common goal. In order to achieve symphonic cooperation, players not only practice together, but they develop strategies where each player follows a role in a larger team effort.

A low-level character being given high-level equipment, usually from a high-level character, that the low-level character wouldn't normally be able to acquire on their own. This places them at an advantage compared to other characters around their level whose equipment tends to match their level. The term is often used derogatorily and is based off the slag term "twink" which refers to a smaller effeminate gay man with a larger boyfriend.

waterfall development model

A game development model that is broken up into clear sequentially ordered stages such as planning, design, implementation, testing, and distribution. At the completion of each stage, the next one begins, with progress flowing in a single direction, like a waterfall. Publishers prefer this model because it makes it easy to track the progress of a game's development. Although this model typically works well with application software, where the goals are much more obvious from the start, video game development doesn't thrive under such a rigid structure. Much of a game's development requires designers to figure out how to make something fun, which often leads to reworking or scrapping segments when they're discovered, far along in development, to not be enjoyable. The waterfall development model is often contrasted with the agile development model.


Describes an attack by a number of enemies at a time. Similar to a level, except the player's character usually remains stationary while the enemies come to her.

weighted random

Random values that are influenced by other factors, typically used to prevent long runs of similar values. For example, if a game uses a random number to determine whether a player hits a foe, they will eventually get a random sequence which causes them to miss many times in a row. Despite this being a product of randomness, the player will probably find this annoying and may think the game is cheating. To prevent this, developers often add various weights to their randomness to ensure that players don't see long runs of similar results, perhaps by continuing to increase the chance of a hit each time the player misses until a hit is guaranteed.


Occurs when a player successfully completes a game. Also referred to as beat, complete, finish, etc.
