The elemental tetrad's third quadrant is aesthetics. And aesthetic considerations are an essential part of enhancing any experience. A game's artwork has the power to transform it. We must always keep in mind that we are creating an entire experience, not just game mechanics. It makes sense to look at your game artwork through a range of lenses, since the ability to see is essential to making great art.  Really look at it: its forms, colors, sizes, shadows, reflections, and textures, as well as its connection to its surroundings and the people who use it. Illustrations are concrete, whereas game designs are abstract. There are only two styles of well-known game designers: those who make "god games," such as Will Wright, Peter Molyneux, and Sid Meier, possibly because it's easy to picture a world's creator as its god; and those who have a distinct visual style, such as Shigeru Miyamoto and American McGee.
