Why are PS3 installs so small?

On the 360 it installs the entire disk, there usually about 6GB's or so. With the PS3 some are only like a couple hundred MB's.I'm just wondering why it even installs anything at all? Is it maybe just a security thing?

I think the installs improve loading time

The PS3 is too slow to read off the disc and have some games play properly

So they install certain parts of the game (various sizes some even consisting of a way to get to and from loading screens) to solve that problem

If the PS3 was faster it wouldn't even need those installs, but it is so we have them

it dont install the entire game, just parts of it because blu-ray drive isnt as fast as dvd therfore its ther to shorten load times

you are obviously not installing the whole thing it's just there to increase the loading timesfunsohng

what? bioshock was 5gb, res5 was 5gb and gta was 3gb ps3 has horrible installs.Javieralijandro

That's what she said.radiocreed

Lol the installs are already big enough, MGS4 and DMC4 are 6 and 5 gigs. Through this is done to compensate for ps3's slow blue-ray speed. I upgraded to a 250gig HD so wouldn't have to worry about space and games load way faster then without install.
