1. So my dad wanted to play NHL 12 on my PS3, that I bought with my money, and Skyrim was still in there, he took it out, but his fingers are chuby and left like a quarter of a figerprint om the edge of the disc and somehow there's something on the PS symbols at the middle of the disc at the bottom, cleaned them both, like you can't see them anymore, will it have an effect on lag?

2. Will legendary edition be on the PlayStation Store? For Download? This is to avoid disc problems.
