Video game designers write the blueprints for computer games. They create the mission, theme, and rules of play.

Most video games are developed by teams of workers. Usually, there is a lead programmer and a lead designer plus artists, musicians, and a lot of programmers. The lead designer develops the overall concept and feel of the game. Depending on the game, the lead designer develops a story line or rules.

It is the responsibility of the lead designer to produce a design document to explain the vision of the game in detail. This document includes the story line, charts, graphs, and sketches.

The lead designer is unlikely to create all of the art in the design document. The designer generally assigns this work to other game designers called level designers. These designers work on their assigned projects and meet with the lead designer to discuss their work. Designers must be able to communicate their ideas and needs clearly. They must also understand technology.
