The document discusses different artistic styles used in computer games including photorealism, cel shading, abstract art, and exaggerated styles. Photorealism aims to make games look like real photographs while cel shading gives graphics a hand-drawn look like comics. Abstract games use simple shapes and colors without realistic elements. Exaggerated games feature unrealistic elements like super powers but still show human emotions. Examples of each style are given such as Minecraft for abstract and Dragon Ball Z for exaggerated.
