To my regret I've never been one to hold onto boxes for games I bought new in the past, and games I buy nowadays I tend to just get loose copies. I'm just wondering if it is worth the investment for some kind of protection for these games or if it's just overkill. I mean if they dust up a simple clean would do the trick anyway wouldn't it?

The only system I've run into real problems with dust is of course the nes.
