Its probably all uncompressed data put on the disk multiple times so it doesn't have to have an install.

Uncompressed 7.1 Audio, 9+ languages, the game should take 10GB.....the uncompressed audio another 10GB...and 15GB of pure voiceovers?

360 DVDs hold no more than 6.8 GB of gamedata, so with equal level quality audio and textures 6 DVDs and potentially even 7 as developers usually resort to data duplicated when spanning a game on multiple discs (for consumer convenience).

It could probably fit into one DVD easily with a next generation GPU. They could do all the lighting prebaked into textures in real time. I suspect this type of game will be uncommon in the next generation because of this. 10:1 vs 8:1 texture compression helps as well.

that's a lot of quick time events... oh sorry thought this was heavy rain.

thank god for blu-ray (and Sony) so we can play amazing games and the industry keeps moving forward into the true next generation.

Cant wait for this game and its amazingness

Can you provide a source? I only read about their advanced HDRL technology, thousands of dynamic light sources and quadrupled resolution for textures.

I think the only option to make the data that small would be procedural synthesis, which almost always results into far inferior end results compared to hand drawn assets.

i quote an Article from the Sixthaxis:

"Tim Moss, Director of Technology at Sony Santa Monica has confirmed that the European version of God Of War III takes up more than 40GB of Blu-ray space. “In low 40’s,” he said, “9+ languages.”

Moss previously said that the US version is around 35GB, so that means that the languages spoken by Kratos and pals alone is greater than the capacity of a standard single-sided DVD."

@ WilliamWatts

And of course, such a level of procedural synthesis requires a large amount of processing power. The Cell can do that (it's awesome for decoding as well as procedural synthesis), but for some games one may prefer to utilize this horsepower elswhere.

Procedural synthesis besides the inferior end results also take more time to develop. So I think produral synthesis of assets will likely remain an additional option for some parts of games rather than taking over for the foreseeable future.
