One of the best looking games at E3 wasn't because of a photorealistic style, but rather what might be called the next evolution in cel shading. Ubisoft called it an "illustrative" style, and it was a distinguishing style for the newest Prince of Persia video game.
Ahriman has invaded the lands and his corruption is evident in the bubbling black ooze. The prince, who is still learning his way to be a prince, has teamed up with the beautiful Elika, a princess who has potent magical powers, potent enough to drive away the corruption and restore life to the lands. Thus, it's a new rejuvenation of the storied franchise.
