Being a pathetically dedicated Metal Gear fan, I splurged a bit on the ps2 Metal Gear Solid Collection, which includes MGS1, and the special editions of MGS2 and 3. Those of you who have played, can you tell me some of the new features of MGS2 Substance and MGS3 Subsistence? (And before someone LOLZ, I did not shell out much extra for these so I was not ripped off/ wasting money, thank you.)
