According to the ESRB, this game contains: Mild Cartoon Violence
Parents have no objectionable content to worry about with Animaniacs: Lights, Camera, Action! Violence is squarely Loony-Toonish (an explosion here and there, but no blood to speak of), and there isn't even a Disney-esque love interest in any of the Warners' three films. The game's quality, however, is much more offensive. Because of lousy hit detection (e.g. the game's ability to tell if the apple Yakko just threw hit its target or not) and poor game design, Lights, Camera, Action! is challenging in all the wrong ways. It frustrated the jiminy out of me on more than one occasion, and I'm in my twenties.
Fans of the Animaniacs cartoon can pass this one up. This videogame is not at all as funny or as well-writtene as the show that inspired it.
Deaf and Hard of Hearing gamers shouldn't have any more problems playing Animaniacs: Lights, Camera, Action! than the rest of us. The story is told in text and there are no significant auditory cues.
