You seem to be beating yourself up over condition a little too much it seems. I used to be the same way but it can really take it's tole. OCD and old games don't mix well lol. This is only my opinion but video games are made to be played, held, opened. Enjoyed. Not relics trapped behind glass with not an ounce of dust on them being awed at as some sort of modern art masterpiece looked at with a monocle. When I first started collecting I was under the impression that if something had the slightest sign of wear it was ruined. Until I realized collectors play their games, hold them, enjoy them. Not clammer about what type of dust particle is on the pins or what not.
Having the idealogy of chasing perfection to increase value is troublesome. It can really cause problems when collecting old things that almost always have some wear
. While you never want something in bad condition of course and the cleaner the better their will almost always be imperfections on items of this age. Minor or severe. As for the crease on the box, it's noticable to someone looking for it. But not at all major and nothing that most people would even care about when inspecting the item for what it is which is a rare game that also happens to be brand new. No item is pristine or perfect. VGA grading has put this false stigma in collector's heads that their games are worst or lesser if they haven't been blessed by the virgin mary herself or have a slightest microscopic strand of corner fuzz.
One of the big things I noticed in the post was when you said "It bothers me not because of the damage itself but because it'll take value away for other collectors". That is a very haunting and digressive thinking to have. To only buy to impress other smug collectors as they stare at your games with magnifying glasses sipping their fine gentlemen's scotch, anything less than perfection getting you the smug snark of disapproval as they look down at you through their nose. Who cares what they think. Are you a reseller? Are you a enterpenuer using video games to attempt to get rich? Do you plan on selling your games after many years like some sort of savings inflation or war bond? If so i'd suggest houses and cars as they are worth more to invest in and usually turn higher profits. If the games are for investment and not to be loved and played than that's the biggest mistake. The value of games is held at such high acclaim with collectors when really it's pointless if you're not selling it anyway. It's fickle. Coming at it with the attitude of hoarding treasure for "value" rather than enjoyment is the issue here and chasing perfection is chasing lies. It doesn't exist. I'm not saying you shouldn't always want the best and most perfect things when collecting but you should never beat yourself up over minor differences or because of "worth" or for the false approval of others but because you like it and love the game.
he only thing that matters about the game is if YOU like it and if the crease bothers YOU.
Not what some smug collector will think. As a collector although only one of many I can tell you it's an amazing piece and in amazing condition. If the crease bothers you that much than i'd say return it but being so anal over imperfections will make it tough to even buy or enjoy old games in the future. Most copies of games have worst imperfections from the factory let alone after 10+ years of being around.
Edit: After relooking at the images, That dent is so minor I didn't even notice it in 3 of the 4 pictures.
. I notice the finger prints and smudges on that glossy black much more. I can't stress how minor and non invasive it is. I hope this helps with you feeling bad about it. It's really not bad. If you do end up returning it I would because the seller lied or didn't show good enough pictures. Not because of the damage itself.
