The first COVID related? short run FOMO I had was with Disaster Report 4: Summer Memories. It's a PSVR compatible game, which I collect, and originally showed up on Amazon for $49. I decided I wouldn't pay a penny over $29 for the game and waited for the inevitable price drop. Well, it didn't drop in price, it just disappeared from inventory's entirely. I deduced that a niche game like Disaster Report might have gotten an extremely small print run, panicked, and bought the first copy I could find on eBay for $99. About a year later Disaster Report 4 reappears on Amazon for $19 or $29, I forget, but I will always remember my stupid panic purchase.
I can still believe that a game like Disaster Report could get a very small print run. It did not, but I could have understood if it did.
Now Metroid Prime Remastered? No way. This first run may have sold out, but that game will be reprinted ad nauseam. Final Fantasy Pixel Remaster strikes me the same way. There were plenty of Asian English versions to be had and Play Asia mentioned there would be a second print run for those. With all the North American customers squalling at Square Enix, I'm hedging that another NTSC print run will find it's way to Amazon eventually. And if it doesn't? Well weren't they kind of acknowledged as perhaps being some of the the worst versions of the games? I know the collectors won't care though. I think the Tales of Symphonia Remastered is getting panned as well. Makes me glad I've kept the original versions.

I believe Best Buy still sells Switch NTSC versions of Live A Live on eBay. Target sells this version too. Some are not happy with the English translation on the Switch version...

Of course the English fan translated SNES cart is still pretty easy to find. I heard a group called Aeon Genesis was responsible for that translation. Ali express will ship a boxed English cart of Live A Live for about $20, but I don't know about the translation origins.
