The document discusses different art styles used in video games, including photorealism, cel shading, stylized, abstract, and exaggerated styles. Photorealism aims to make games look as realistic as possible, but may limit creativity. Cel shading uses flat colors instead of smooth lighting to create a distinctive look. Stylized and exaggerated styles cartoonize proportions while keeping some realism. Abstract art employs shapes and colors without realistic resemblance. Each style suits different genres and gameplay.
