According to ESRB, this game contains: Animated Blood, Animated Violence
Parents will note that, although not as graphic as many games released on the market nowadays, Castlevania 64 does offer its share of violence, blood and dead bodies. However, the language found in the game represents nothing to worry about. Basically this game lives up to its "Teen" rating, as it would be inappropriate for young children while offering nothing too gory to restrict it to a more mature audience.
Fans of the Castlevania Series will be disappointed with this game as it fails to live up to the success any of the previous games have received.
Bad controls and a frustrating level of difficulty will most likely alienate Platform fans. This failed attempt at creating a 3D game for a popular franchise will be forgotten easily and only looked back upon as the black sheep of the family.
