yeah the illegal version with the portion is 3GB the retail is around 5.2GB. it's bigger than a DVD 5.
there´s one thing i forgot. quality. as i speak, i have a CD with the movie silent hill.
yes, a CD.
my friend got one at filewarez because the movie is not out yet in our town. its a ripped file, compressed and stuff. takes less than 700 mega... all movies that you rent come in a DVD-9. if you want to rip them, you can compress and put it into a normal DVD. if you really compress, it fits a CD.
but of course, the quality is not the same. certainly not HD.
and this aplies to GT4. if you try to rip the GT4 disk, it will show 2 files, the iso of 4 gigs and other file of 1 gig. still, that´s not all the info needed, that´s why most of the first pirate copies had bugs, crashed, or didn´t had the whole game in it. trust me, piracy is big here. GT4 took a lot of time to get to the market because it wasen´t so simple to rip the DVD and make it work 100%. that´s why pirate copies today are in DVD9. they realised that they couldn´t compress something that was already tight.
and what does all of that have to do with the PS3 and this thread?
a lot. its about quality, and i think this is what we´re going for in this next gen. i can have silent hill, the same version as the one that later on will be released in BD, in a single CD.
but does it have the same quality?
of course not.
technology evolves and with this, we discover many ways to compress data without losing much of quality. still, we have to reasonable, tech still didn´t found a way to put HD content into a single CD.
that´s why micro$oft was heavily critisized for lauching the 360 with DVD. because they wanted the pole position, not worring about the race. they wanted to be first in the market, and they released the console before the BD x HD-DVD thing was set. they didn´t wanted to pay royaties to sony and didn´t wanted to wait on HD-DVD. then they shoot themselves in the foot launching a brand new console with an old media storage.
so its fine, as long as you don´t really care about quality, to have things compressed and missing things... but then again, i don´t think this is what next gen is all about...
