Noticed this thread just now...a guy I work with put a serious addition on his house over the course of the last few years. Part of the reno was to add to the basement: he added an all concrete room to house his video game collection. It's worth well north of $150,000. From talking to him, I suspect that article (the link goes nowhere currently) is about the Nintendo game that was only released on a very limited basis in Japan, and only about 5 of the original boxes for the game exist, and 4 are in lousy shape, and the one in the auction was the best one known.
Apparently, the original boxes and instructions are what drives the value of these things up. I told him my mom used to take the boxes from new Atari games we got as kids, fold them flat, put the instruction books in them, and put them in a box. We had around 100 of them, and somewhere along the line they got tossed. Guy said that they would be worth thousands now, especially if the games were obscure.
Guy isn't some incel, either....funny, smart dude, married to a woman where he kicked way outside his coverage and has a couple of kids he's really involved with.
