To each their own, and if someone wants to pay through the nose for a sealed copy of a game, so be it. Who am I to judge how someone spends their money?
But they could at least consider looking for sealed copies of their PCE counterparts. Then the artwork would be worth looking at. In most cases the TG version had really crummy artwork compared to the PCE counterpart. If it's just going to sit there looking pretty, at least it could look pretty.
There's a thread here comparing artwork and if I had better search mojo, I'd add a link to it.
