How can a blue-ray disc support GTA 5?!?!?

[iamlegend]

I mean with a map bigger than red dead, san ansreas and gta 4 COMBINED.. + 30-40 hour story mode and of course multiplayer.. HOW???

[nightmaresarereality]

very very easy,, a dual layer BLU-RAY ( NOT BLUE-RAY) can hold 50gb of data, compare that to a dual layer dvd which can only hold 8.5gb of data

so if gta 5 uses 41gb of data the xbox version will need 5 dvd discs to hold the data, while the ps3 still needs only 1 blu-ray disc
