Is proving a real challenge.

Speaking to VideoGamer.com earlier this year Quantic Dream founder David Cage revealed that the decision to release a playable demo for upcoming PS3 title Heavy Rain had not been made, explaining that the game is difficult to accurately represent in demo form.

"There are some big debates at the moment within Sony about the proposal and the interest of a demo," Cage told VideoGamer.com at gamescom. "Even to make shows like Cologne, it's a real nightmare to pick out one scene and say, look, we're going to choose one scene and people will understand what this game is all about."

He added: "Honestly I don't know at the moment. There are pros and cons to doing this."

Speaking more recently with G4, Cage confirmed that the decision has been made to produce a demo, but the challenge of accurately representing the game remains.

"We are currently working on a demo, which is a real challenge," said Cage. "Finding one scene that can convey what we are trying to achieve with Heavy Rain is something really difficult."

He added that releasing a demo is required because Heavy Rain is a new concept to gamers.

"We also know many good games that ended up not being massive hits because the demo could not convey the quality of the game behind it," he said. "Because Heavy Rain is a new concept and since many gamers will want to check what it is before buying it, we will be releasing a demo. We just need to find the best scene for it."

Heavy Rain is scheduled for release only on PS3 in 2010.
