Heavy Rain is a "dark, immersive and emotionally-engaging experience" expanding upon the ideas of Quantic Dream's previous adventure game, Fahrenheit (Indigo Prophecy). Once again, the promise is that "every action has a consequence" with a constantly evolving story based on the way you interact with others and the choices you make. SCEE is promising it will talk about topics unheard of in gaming, "making it a genuinely mature game for a new world of adult gamers."
