I think it makes sense. This is the Superman #1 of video games.
No, it isn't. This is a useless shitty game isn't any f*cking fun at all, commonly available in multiple, slightly different versions from the same period for $1 (if that).
Superman #1 (I assume you probably mean Action Comics #1) broke ground, kicked off a hugely successful franchise, and was actually sort of good. This...isn't. A $40,000 NES game that everyone knows sucks and will never be opened or played is just a artifact of a hugely rich and hugely bored society that has run out of ways to entertain themselves by spending money. Even if one views market-concious "video game collecting" as a non-horrible thing, this is completely outside of that. This thing is bullshit.
Somewhere in Slovenia some dudes with furry hats and new credit cards are in a bidding war over the only known Dendy copy of Bible Adventures localized for the Soviet Union. COMPLETE IN BOX!
And they are dumb-asses too.
