This PowerPoint presentation discusses different art styles used in video games including photorealism, abstract, cell-shading, and exaggerated styles. Photorealism aims to recreate realistic images and is used in games like Call of Duty and Grand Theft Auto to make environments and weapons appear real. Abstract games like Geometry Wars and Eufloria do not represent reality and use geometric shapes and relaxing colors. Cell-shading is used to make 3D graphics appear flat through less shading, seen in Dragon Ball Z, Borderlands, and Zelda. Exaggerated features are larger than real life, seen in fighting games like Tekken and Mortal Kombat through oversized characters and powers.
