Every art form is expressed through a physical medium. The control and manipulation of this physical medium is a technical problem that the artist must master before she can express herself through it. Thus, the sculptor must thoroughly understand the limitations of marble, brass, or whatever medium she uses. The painter must fully understand the technology of paint and the behavior of light. The musician must be deeply skilled in the technology of sound creation. So too must the computer game designer thoroughly understand the medium with which she works. The computer offers special possibilities and imposes special constraints on the designer.
