...because it wasn't the arguement. Since you bring it back up.

Artwork and music don't have much to do with the development process unless they're needed. The biggest part of development is planning and execution.

Because you're forgetting one little thing... development isn't design. Adding artwork or music doesn't develop some thing, but it relates to design of that particular object. Thus art and music have little to do with the development of the game, outside the base API coding you ought to be past anyway, but are keys in design.

Get it?
