Easily one of the most beautiful cel-shaded games around, Okami's art style shows what the potential of cel shading can do to make a game look gorgeous. (Okami sports a style reminiscent of a Japanese ink wash painting).
The gameplay also suits the graphical style as you use a paintbrush, known as the Celestial Brush, to attack enemies and progress through the story.
The sequel, Okamiden, which was praised by critics, also uses a cel-shaded style
While no sequel has been announced, who knows what the future will hold for this series. It would be wonderful to see these graphics enter the current generation.
