After I started to get into collecting I looked up how to maintain games and systems and such, and saw that many problems were caused by dirty contacts and I thought dam and I lost all those dust covers for me snes games years ago not thinking they were very important.

So instead of getting more of those covers I went the cheap route and made my own out of paper(and they work pretty well).

Then watching AVGN videos I noticed that when he pulls out his NES games off the shelf he never seems to have any sleeves on them, so it brings me to ask the question:

How important is it to put the game in those sleeves and also what do you guys do with your games, go naked, cover them, insist on licensed covers etc.
