How are video games made? Game studios rely on teams of people, such as designers, programmers and artists, to make video games. You may have heard that one person makes a whole video game. In fact, most are built by teams of designers, artists, programmers, sound people and testers. Programmers do the technical work that makes a game's ideas work, and artists make the pictures in a game, such as its characters. A game has sound effects and music, and people on the team work on them. Easy coding tools let kids and other beginners make their own games. The art director keeps the overall style and look of a game consistent, within time and budget limits.
Art and design staff are expected to work closely with other teams, balance quality with performance, and make sure the assets they make function. Programming jobs in real-time projects such as games create the functionality, including gameplay, networking and artificial intelligence. Programmers in game roles spend most of their time writing and revising code, researching new techniques and optimizing their projects for performance. A gameplay programmer builds systems such as the player's actions, character behavior, game elements and game progression. A localization specialist translates, tests and adapts a game so it works for players from different backgrounds. Writers help make a game's story and characters. Artists use programs such as Blender to make 3D models and other art for games.
Game designers write detailed game design documents that outline visual mockups, mechanics, features and workflows. Small changes to movement speed, timing, collisions or controls can change how a game feels. Game designers plan how a game is played. Level designers build the places and levels that players play through. Animators make the characters and objects in a game move. A prototype is a simple early version of a game that a team builds to see if an idea works. In an early prototype, a player character might be a floating capsule and a level an empty room. Game development is the process of designing, prototyping, building, testing and refining a game.
A game engine is a software platform with the tools a team uses to build a game. Games are made of smaller pieces such as 3D models, scripts and audio files, and a game engine is where all the parts of making a game come together. Inside a game engine you do not create assets, because assets such as objects and sounds are made in specialized outside programs called digital content creation tools. Different game engines suit different games: some make 2D visual novels and others suit 3D sandbox games. Unity is a game engine used to make both 2D and 3D games. Godot is a game engine that can make both 2D and 3D games.
A QA tester is the last line of defense between the consumer and a broken product. If a bug gets into a released game, players will find it, so testers try to find bugs first. A game QA tester notes each possible bug, the steps to reproduce it, and how serious it is: low, medium, high or game-breaking. After developers mark a bug as fixed, the QA tester repeats the same steps to make sure the problem is gone. A QA technician finds and reports bugs and writes test cases and plans. Designers have people play a game and use what they learn to change it. Game testers do not just play games for fun.
Pong did not come first. In 1958, a scientist at a laboratory in New York helped make Tennis for Two, an early electronic game that visitors could play. Spacewar!, made at MIT in the early 1960s, is one of the earliest games for a digital computer. Magnavox released the Odyssey in 1972, shortly before arcade Pong, after six years of work by its creator Ralph Baer. Atari engineer Allan Alcorn built Pong after his boss asked for a simple game based on Ping-Pong, and the first Pong machine, in a Sunnyvale, California, bar, stopped working because it was full of quarters. Soon after Pong came out, Atari had tens of thousands of copies in restaurants and bars across the country, and the arcade era had begun. Next, Pac-Man. Its designer, Toru Iwatani, says the name Pac-Man comes from the Japanese paku-paku, an imitation of the sound of eating. The Strong museum calls it the best-selling arcade game ever.
Video games are played on many kinds of machines, such as computers, game consoles and phones. More than 205 million Americans play games, according to the ESA's 2025 Essential Facts report. In the ESA's 2025 report, 82% of players age 8 and older used a mobile device to play games. In the ESA's 2026 report, the top two reasons Americans play games were to relax and to have fun. A 2017 conference abstract said that reward schedules, operating on operant conditioning principles, may encourage excessive gameplay behavior. An ESRB rating of E means the content is generally suitable for all ages, as of November 2026. As of November 2026, the U.S. game industry creates and supports more than 250,000 jobs and about $95.8 billion in total economic impact, according to the ESA's 2026 report.
