Mystery Case Files is a series of Casual Video Games from Big Fish Studios. Despite its title and slogan, no actual sleuthing occurs; it's actually a Hidden Object Game, a genre which became popular with this series. The Ravenhearst Story Arc subseries is arguably the most famous line of titles to come from the Big Fish developers. Although the plots of all of the games in the arc are not related to the events at Ravenhearst Manor, you play the same Master Detective in all of them and there is a tangential connection in each one.
