Video games grew from laboratory experiments and blinking oscilloscope dots into a global medium spanning phones, consoles, computers, virtual reality, museums, competitive arenas, and enormous online worlds. Their history is filled with accidental mascots, hardware limits that became art styles, cartridges you really should not blow into, and design tricks players barely notice. These 145 facts explore the technology, history, genres, controllers, graphics, sound, esports, and culture behind gaming.
Video game basics
- A video game is an interactive electronic game displayed through a visual system.
- Video games can run on consoles, computers, phones, tablets, arcade machines, and specialized hardware.
- A game engine provides reusable systems for rendering, physics, audio, input, and other functions.
- Not every video game uses a commercial game engine.
- Game code determines rules, logic, interactions, and responses to player input.
- Graphics can be two-dimensional, three-dimensional, text-based, abstract, or photorealistic.
- Players interact using controllers, keyboards, mice, touchscreens, motion sensors, cameras, or other devices.
- A game loop repeatedly processes input, updates the game state, and draws results.
- Frame rate measures how many images a game produces each second.
- Resolution describes the number of pixels used to display an image.
- Higher resolution does not automatically make a game more fun or artistically effective.
- Latency measures delay between an action and the system’s response.
- Low latency is especially important in fast competitive games.
- Single-player games focus on one player’s experience.
- Multiplayer games let two or more people compete or cooperate.

- It was later widely known as the Atari 2600.
- The Atari 2600 used removable cartridges containing game data.
- Its success helped establish the cartridge business model.
- Limited memory forced developers to use remarkable programming tricks.
- Early console graphics were built from tiny sprites, simple shapes, and repeated patterns.
- Programmers sometimes reused the same memory for multiple visual purposes.
- The recognizable pixel-art look partly grew from severe hardware limitations.
- Cartridge contacts can oxidize or become dirty over time.
- Blowing into game cartridges was a famous player habit.
- Moisture from breath can actually promote corrosion rather than providing a safe cleaning method.
- Cleaning contacts properly is better than treating an old cartridge like a birthday candle.

Arcades create a gaming boom
- Arcades became major social gaming spaces during the late 1970s and 1980s.
- Space Invaders was released in Japan in 1978.
- Its accelerating enemies created increasing tension as a level progressed.
- Asteroids arrived in 1979.
- It used vector graphics rather than ordinary raster sprites.
- Pac-Man debuted in Japan in 1980.
- Pac-Man was designed by Toru Iwatani at Namco.
- The character’s simple circular design became one of gaming’s most recognizable icons.
- Donkey Kong debuted in arcades in 1981.

How 3D graphics transformed games
- Three-dimensional games existed long before consoles could render detailed polygonal worlds.
- Wireframe graphics represented 3D objects using lines instead of filled surfaces.
- Polygons became the basic building blocks for many 3D game models.
- Textures place detailed images across polygon surfaces.
- Lighting calculations help create depth, mood, and material appearance.
- Perspective projection makes distant objects appear smaller.
- Texture filtering reduces harsh pixel changes as surfaces move farther from the camera.
- Anti-aliasing helps smooth jagged visual edges.
- Level of detail systems can use simpler models for distant objects.
- This saves processing power where fine details would barely be visible.
- Real-time rendering must create frames quickly enough for interactive play.
- Pre-rendered graphics can look more detailed because they do not need to be calculated instantly.
- Ray tracing models paths of light to create realistic reflections, shadows, and illumination.
- Modern games often combine traditional rasterization with selected ray-traced effects.
- The graphics processor, or GPU, performs huge numbers of parallel calculations needed for modern game visuals.
Online games and esports
- Multiplayer computer gaming existed across networks before the public Web.
- MUDs were text-based multiplayer virtual worlds that flourished on early computer networks.
- MUD stands for Multi-User Dungeon or closely related expansions.
- Online games require systems to synchronize player actions across network delays.
- Lag is the visible effect of unwanted network or processing delay.
- Game servers often act as authoritative referees for shared online worlds.
