Parents should not be concerned about letting their kids have access to this game. Like most Nintendo titles, Animal Crossing is incredibly kid-friendly in terms of mature content. Not only that, but Animal Crossing boasts a world that rewards positive, socially outgoing and responsible behavior from the player. Add in the possibility of child-parent interaction inside the game, and this game is a winner for households with children.
Hearing impaired gamers have nothing to worry about. Although they will miss out on the game’s music and burbling speech of the animals, all relevant information is conveyed by text. (There is a significant amount of music to collect in the game, so that may be an issue if you feel that you would be left out.)
