Why do games on the DS look so bad but Professor Layton cutscenes are really good graphics?

Games on the Nintendo DS often had simpler graphics due to the system's limited hardware capabilities, which restricted the resolution and polygon count. In contrast, Professor Layton cutscenes used pre-rendered graphics and higher-quality art styles, allowing for more detailed visuals that took advantage of the DS's capabilities. Additionally, the game's distinctive art direction, which emphasized a storybook aesthetic, contributed to its visually appealing cutscenes. This combination of artistic choice and technical execution made Professor Layton stand out among other DS titles.
