You are right on track: this technique and the derived (generic) style your images have in common are called cel shading, named after the transparent celluloid sheets that are used in classical comic and animation production:
These sheets are used to separate animation from the inanimate background and static props. On them, the outlines are usually drawn on one side, and the objects coloured in on the back, giving crisp outlines.
These outlines are rendered in 3D using edge detection, to simulate a flat character. To the same effect, real-time lighting effects are often a lot less gradual (i.e. it is quantized). This can be seen clearly on the pants of the Naruto Skin shader, whereas Telltale opted for a more subtle lighting, balancing TWD's art style between the comic style of their source material and the realism the emotionally heavy storyline demands.
