Photorealism aims to depict objects and scenes as realistically as possible through detailed textures and polygons, though it increases development time and file size. Cell shading renders 3D graphics to mimic a hand-drawn comic or cartoon style, giving games a simplistic feel. Abstraction uses minimal details and Tetris is an example of this style. Exaggeration is common in anime-inspired games and is designed to be over-the-top rather than photorealistic, creating a more fun atmosphere.
