I disagree with this. Something could be "hard to find" because sometimes you literally can't find it anywhere, but that could just mean that the collectors who have it in their possession just aren't making it available. A limited print Switch game that just shipped may only have 3,000 copies in existence, and yet because it's mostly in the hands of resellers, you'll find 30 listings for it on eBay. But keep in mind there are only 3,000 copies of the game. Meanwhile there are plenty of retro games that people consider rare that now only show up with a few copies on eBay or less than that. But we have some idea of how many copies actually exist. Like NBA 2k3 for GameCube or Shepherd's Crossing 2 for DS. There are at least thousands of copies of each one. I would argue that both the Switch game that just shipped and these older games that are now hard-to-find are equally rare regardless of how many copies are listed on eBay. Once that Switch game ends up in the hands of collectors who have no intention of letting them go, then it's considered rare? Because in a few years it's not being listed on eBay anymore? I don't get it.
