A video game developer is a software developer that specializes in video game development – the process and related disciplines of creating video games. A game developer can range from one person who undertakes all tasks to a large business with employee responsibilities split between individual disciplines, such as programming, design, art, testing, etc. Most game developer companies have video game publisher financial and usually marketing support. Self-funded developers are known as independent or indie developers and usually make indie games. A developer may specialize in a certain video game console (such as Nintendo’s Wii U, Microsoft’s Xbox One, Sony’s PlayStation 4), or may develop for a number of systems (including personal computers). Video-game developers specialize in certain types of games (such as role-playing video games or first-person shooters). Some focus on porting games from one system to another, or translating games from one language to another. Less commonly, some do other kinds of software-development work in addition to games. Most video game publishers maintain development studios (such as Electronic Arts’s EA Canada, Square Enix’s studios, Activision’s Radical Entertainment, Nintendo EAD and Sony’s Polyphony Digital and Naughty Dog). However, since publishing is still their primary activity they are generally described as “publishers” rather than “developers”. Developers may be private as well (such as Bungie, the company which developed the Halo series exclusive to Microsoft’s Xbox).
