Cage: Heavy Rain sold four times more in US than Sony had anticipated

We already knew Heavy Rain was an immediate success in the UK and a moderate hit in Japan. But with the game's quick disappearance from the NPD's monthly top ten in the U.S., we've been wondering whether the game's sales on this side of the ocean (which NPD pegs at just over 400,000 units so far) have lived up to expectations.

Well, "lived up to expectations" might be a bit of an understatement. At a GDC Europe talk this week, Quantic Dream CEO David Cage said Heavy Rain ended up selling "four times as many copies" as publisher Sony expected. "They were shocked. 'Oh my god, what happens?'" Cage said in his charmingly stilted English.

These unexpected sales presented a bit of a problem, Cage said, because the marketing spend for the game was based on the lowball expectation, not the surprisingly strong actual sales numbers. Still, Cage said Sony did a great job pushing the game in the States, especially considering the game's unorthodox concept and lack of a big franchise name, which led to some reluctance from distribution channels.

Cage said Heavy Rain has already sold 1.5 million copies (up from one million in April) worldwide and the game is on track to sell two million units by the first anniversary of its February release.
