One of the major reasons for the huge file size of MGS4 was the Octocamo. The feature required so many textures and due to the texture saving feature, they had to all be available at any time. It was the huge number of textures, combined with less advanced compression capabilities that really pushed the size up. Not to mention, PS3 development was much harder back then. People weren't used to its strange architecture.
