The benefits of the higher storage capacity of Sony's Blu-Ray discs have once again been pulled into the spotlight as Heavenly Sword chief development 'Ninja', Nina Kristensen, tells CVG that the game would simply not be possible on DVD.
"We have jam-packed the Blu-Ray disc absolutely full," declared Kristensen, as she confirmed rumours that the audio alone was allocated 10GB of space on the 25GB Blu-Ray discs.
That's more than an entire dual-layer DVD game, which holds a total of 8.5GB.
We wondered if this meant compression methods usually used to squeeze content onto normal DVDs had not been used, but Kristensen insisted otherwise: "We used compression all over the place. We had to be really judicious at the end with what was going on the disc and what wasn't.
"I think it's one of those things - if you give us the space we're going to fill it with stuff. It means the audio can be of a higher quality and stuff like that. It all adds to the quality of the package," she told CVG.
