Okami (Playstation 2)

In Okami, the player takes the role of the mythical sun goddess Amaterasu, in the form of a wolf. Her task is to restore color (or 'life') to the world by destroying the monsters who have stolen it. Since Amaterasu is a diety, there are naturally people who worship her and people who don't. The more people who worship her (as a result of her restoring color and doing other good deeds for them), the more powerful she becomes.
