Speaking to NowGamer at E3 earlier this month, Quantic Dream's David Cage revealed that there's still plenty of work to be done on ambitious PS3 exclusive Heavy Rain, adding that the game has to be perfect.

"We’re still at the alpha stage and there’s a whole lot of work to be done," said Cage. "There’s so much fine-tuning in the game left to do. Everything has to be perfect. If there’s one thing wrong in a scene, it’s the only thing you’ll see. There are many things that don’t work right now. We need to have everything in place, from facial animations, to score to work out the final result."

Heavy Rain is expected for release early in 2010 only on PS3.
