It starts with an artist (usually experienced in drawing cartoons) and a game strategist (usually experienced in some form of psychology or anthropology) to define the presentation, and strategy. Sometimes, experts in statistics will be called to determine if the difficulty level is appropriate for the target group.

A programmer will then implement the software code in a game-development system that have many supports on graphics and state transitions (how one scene leads to another). If the program runs on PC or PS/2, we are almost set. Just testing and CD/DVD burning will be sufficient.

If this if for a Game Boy, an arcade station or a specific machine, the program is then compiled to a digital-circuit diagram that corresponds to the software specification. If the timing or size of the digital circuits does not meet the requirement, digital circuit designer will come to optimize the circuits. The circuit design is sent to integrated-circuit foundry (big manufacturing site), which will produce the computer chip. Finally it comes to the testing and unit packaging.

The computer game development, like many other full systems such as a car or digital camera, involves many expertises. It is the team effort that will determine if the game is a hit on the market.
