Catherine isn't like other video games. It isn't about saving the world, rescuing a princess, or slaughtering scores of nameless troops. It is, instead, about a regular guy in over his head. That guy is Vincent, a soft-spoken man so afraid of confrontation that he refuses to take control of events that change the course of his life. During the day, Vincent's attempts to make sense of his romantic entanglements lead to fear and desperation. At night, that desperation translates to cruel nightmares in which Vincent scrambles up an increasingly complex tower of emotions.
