Answer: Jet Set Radio
Cell shading is a way to make 3D computer graphics in such a way that they appear to have been drawn as animation cells. The result is a bold and distinctive look that sets shaded graphics apart from traditionally rendered computer graphics. One of the first video games to utilize cell cutting, and a critical title in itself, was SEGA's Jet Set Radio released to Dreamcast in June 2000.
Since then, hundreds of video games made in cell-screen style have been released, including several notable modern games such as the Borderlands series, Ōkami and its sequel idenkamiden as well as Legend of Zelda: The Wind Waker Bastion and MadWorld . While many of these games would remember well for interesting gameplay and storylines, then it was certain that the heavy style of their cell-shaded graphic design left an interesting impression on players (and there is a good chance if you have played any of them, then You already thought of them before we even started listing examples).
