The real shame is that those games will just sit on a shelf 'til the end of time and never be played. Not trying to start a flame war or anything, but seriously, if you're not a gamer, you shouldn't be collecting games. At all. All you people are doing is artificially inflating prices to the point where REAL gamers can't afford the good stuff because even loose copies have gotten WAY overpriced. For example, Earthbound is not that rare and no way is it worth anywhere near what it goes for these days, but because "collectors" decided it was gold, the people who would actually buy that game to play it can't. And there are lots of other examples I could think of, too. It's almost impossible to find a good deal on anything anymore thanks to you people. And don't tell me to "just use emulation" because that is not a defense.
You are correct, and with the grading it got even more insane.
However, the demand is really really high. And speaking about Earthbound, the more time flows.. the worse these boxes become. So the better copies will gain even more value.
The GOOD games are raising, the worse ones dropping.
