I have a question. I've recently been thinking of picking up the Elder Scrolls Oblivion Game of the Year edition for the PS3, and I noticed that it comes with three (or was it two?) of the games' expansion packs. I also remembered how my parents forbid me to create a PSN account for privacy reasons. My question is, do you need to download the packs through a PSN account, or are they already on the disc?
