I, for one, enjoy the "thrill of the hunt" so to speak. For one thing, buying old games on sites such as Amazon or eBay usually means overpaying. Plus, nothing beats the feeling of finding that old, neglected classic on the shelves of a moldy thrift store and hearing the lady say "they're two dollars each." I have quite a few complete games doing it this way.

Though I may have purchased a couple of newer games online for convienience's sake, (I think I got Shenmue for Dreamcast about a year ago from a seller on Amazon), but for the older, hard-to-find stuff, I'd rather pound the pavement. I just think it's more fun.
