I notice that in a lot of personal collections, people have their game collections stacked up with no protection. Be aware that the constant use, flow of dust particles and risk of spillage can damage your games and labels. Take the atari 2600 and coleco type cartridges for instance. What you can do is either go about the cheap way and put each game in ziplock (doesnt look pretty but does the trick) or contact bagsunlimited.com. They have special bags that will fit perfectly over the game cartridges. They also can custom fit over any other game you may own, including nintendo, sega etc. Especially if you own any new sealed games, rare or not, it will keep the corners from getting rubbed and stuff. I've seen I lot of nice collections on this link recently. Might as well keep them that way.?
