I couldn't help but think people would have conflicting opinions over that.
Anyhow, I suppose sealed games do have their margin of appeal. It's not for me, but hey, if you want to display your childhood (or simply something rare) as a trophy for all to see, at least for this generation, I can't think of a better way than your favorite game(s) looking the same way it did when you first discovered it on your Xth birthday/christmas/whatever.
