When comparing the PS3 experience across formats—physical disc versus digital PKG—the primary distinction lies in installation convenience rather than raw gameplay performance. Because MGS4 utilizes a massive 4.6GB mandatory install that caches assets to the internal HDD regardless of format, performance remains largely identical between disc and PKG versions. Performance & Technical Specifications
To understand why PKGs are sought after, you have to remember the pain of the original 2008 release. metal gear solid 4 ps3 pkg better
