Heavy Rain, popular among the gaming industry for taking the road less traveled by, became an unpredictable success in the eyes of many, including David Cage himself. As the estimated numbers show, Heavy Rain managed to sell over 1,000,000 with just over a month of public exposure. Quantic Dream were taking big risks with their vision and expected (like many others) to see a low number and less-than-flattering reviews reflecting it. What resulted was much more pleasing.
The game ultimately met great ratings and great sales as well, equaling a massive success for the company. To journalists in the industry, these numbers proved that the average consumer is absolutely unpredictable. Although total numbers have yet to be released, Quantic Dream's PlayStation 3 exclusive already sold over 1,000,000 copies and manages to hold strong in the Top 20 over a month later.
Past games developed by Quantic Dream include Indigo Prophecy/Fahrenheit. According to QD, Fahrenheit also met commercial success and managed to sell over 800,000 copies since it's 2005 release across multiple platforms. It is unknown exactly how much QD managed to make from their first title, released on PC and Dreamcast called Omikron: The Nomad Soul. However, Omikron 2 has been confirmed to be in the works as of April 2005.
