Yes, but when you program a game that requires multiple discs, data needs to repeat itself from disc to disc.  So even though the amount of storage space totals to be greater, you are required to repeat data (such as the main character to say the least).  Therefore, having more total space amongst several discs might not be as effecient as a single larger storage media.  So your theory of the "lack of space" on Blu-ray doesn't necessarily hold water.


Explain this to me, I don't see what you are saying... 


i think what he means as there are constants on all the disks, as an example, the main characters textures and expressions must be saved on all disks because they'll be called upon from all disks.

another example would be an overworld map. to work in a video game (like final fantasy 7) the overworld map has to be compelete on all disks so each final fantasy 7 disk only had like 400mb of space (out of 700mb) to put actual content because the data had to be redundant across all the disks to ensure you could travel wherever you wanted at whatever point in the game

without being redundant across disks in this case you would either require no exploration to places you have previously been to (final fantasy 13) or disk swapping to access places that you had previously been to (mass effect 2).
