I'm honestly surprised it didn't sell for more.
In this day and age, the only barrier against owning anything is merely how much you are willing to pay for it. Very few things are truly "rare" or "hard to find" anymore given the prominence of online shopping and marketplaces, eBay in particular. However, given our free market system, people are able to charge whatever they want for their items, and likewise, people are able to spend whatever they want to obtain them.
Nothing wrong with this at all, but when the circumstances are right, it's easy for a buyer to get swept up in the moment and overspend on something. Nine grand is a major investment for any sort of collectable, but for this buyer, they felt it was appropriate. I feel like the number of sealed Kid Icarus packages out there must be in the single digits, but as others have said, it's not a terribly uncommon game. No way I would ever consider dropping that kind of cash on something I could never do anything with but look at, but hey, I'm not a collector.
What is a collector? Please don't pepper me with the SOTN meme, I'm being serious. In my eyes, "collector" is just another word for "hoarder." While it's nice to be able to surround yourself with things that make you happy, as the saying goes, you can't take it with you. Some out there have collections of 10,000 games or more, but regardless of the reasons for their collecting, nobody is going to enjoy or appreciate the collection as much as the one who put it together. When they're gone, their friends and family are left with a house full of "stuff."
Again, nothing wrong with collecting, though the prudent thing to do would be to enjoy your items for what they are, but make sure they don't become a burden to those closest to you. Not only that, but anytime you're talking about a collection, there's the risk of losing it through uncontrollable circumstances. Theft. Fire. Natural disasters. Sure, collections can be insured, but if, for example, your house is swept up in a tidal wave (a very, very real possibility where I live) it's all gone. You can't take it with you, but it certainly can be taken away from you.
For the buyer of that copy of Kid Icarus, it was worth the nine grand to have it sitting on their shelf, staring back at them for the rest of their natural existence. For most of the rest of us, we probably have better uses for that kind of money. Nine grand is a lot for any sort of objet d'art
, but it's not much different than having a collection of Faberge Eggs or having a Maserati parked in the garage. Some people feel the need to have physical representations of their wealth that they can display to others, and hey, more power to them.
Me, personally? Nine grand? I dunno, that's a lot of trips to Taco Bell...
