I understand the desire to have a sealed game as a collectible. One day, just maybe one day, you can open it up and the contents will be like brand new.
What I don't get is having the plastic on the outside being in untouched perfect condition...
BUT, if I could get an uncirculated copy of some game coming out soon (say FFXIII), I would seriously consider sending it to VGA just so I could have it labeled "VGA U100 Gem Mint." Of course, I would not pay $900 for a game. But I would pay $59.99 + the $25 dollar VGA fee just so that in ten years (if VGA even matters by then) I can try to sell it on eBay for twenty times as much.
Actually, I would wait until FFXIII was marked down to $19.99 or $29.99, then do that process.
