Computer games / video games are created by game developers. Although these can be individuals, they are usually Studios, where at least a game designer, producer, writer, graphic designers, programmers, level designers, sound designer, musician and game testers work in teams on the development of computer games.
Among the most famous designers include John Carmack, Sid Meier, Peter Molyneux, Will Wright, Shigeru Miyamoto, Yū Suzuki, Richard Garriott, Hideo Kojima, American McGee, Markus Persson, Chris Sawyer and Warren Spector. Most teams comprise 20 to 50 developers, but it can also be greater than 100.
The production of a modern, commercial video game will take approximately one to three years and costs about one million to 15 million U.S. dollars.
The game industry in countries such as Japan differs quite strongly from that in Europe and the United States. So many developers produce anonymously or under pseudonyms. Often the teams in Japan have a dedicated designer (called Director) and are much larger. Since it is difficult to produce games for consoles without a publisher, there are few independent productions from Japan.
Game developers are organized on an international level through the International Game Developers Association (IGDA).
