A little love goes a long way. After the long searches, the negotiations, and the actual transfer of funds for game pak, you have your beloved game in your hot little gaming hands. The first thing you should do is slam it into your game console, right? No! Clean that game pak first, otherwise you'll be playing that game with everyone who has ever played it before. You never know how the previous owner(s) treated the game. Yes, it's possible that it was kept in a crystal shrine on the mantle, but most likely it was left to gather dust, then slobbered on by the family dog (and that's why the game was sold to you in the first place).
