Video game design is the process of designing the rules and content of video games in the pre-production stage and designing the gameplay, environment, storyline and characters in the production stage. Some common video game design subdisciplines are world design, level design, system design, content design, and user interface design. Within the video game industry, video game design is usually just referred to as "game design", which is a more general term elsewhere.
The video game designer is like the director of a film; the designer is the visionary of the game and controls the artistic and technical elements of the game in fulfillment of their vision. However, with complex games, such as MMORPGs or a big budget action or sports title, designers may number in the dozens. In these cases, there are generally one or two principal designers and multiple junior designers who specify subsets or subsystems of the game. As the industry has aged and embraced alternative production methodologies such as agile, the role of a principal game designer has begun to separate - some studios emphasizing the auteur model while others emphasizing a more team oriented model. In larger companies like Electronic Arts, each aspect of the game (control, level design) may have a separate producer, lead designer and several general designers.
