A developer from Ninja theory responds to the recent news about the developers using over 10GB of space for only Heavenly Sword audio.
The developers came very close to using a dual layer blu-ray disc because even with the size of the single layer blu-ray disc, they were having problems fitting all all of the game's audio data onto a single layer blu- ray disc. According to the developer :
"We use a mixture of compressed and uncompressed, but lots were compressed for the reasons people have stated.
Make no doubt, fitting all the audio in and not stuttering and being the the highest quality we could get wasn't easy, it was quite a problem even with the size of blu-ray. At one point we seriously considered dual layer Blu-ray cos of disk space issues."
