/vr/ - Retro Games

So /vr/, I've been meaning to ask the experts on this. How exactly do games become "rare"? Like in our case, Flintstones: Surprise at Dinosaur Peak for the NES. I know this was exclusive to Blockbuster in the USA, but it existed in Europe as well, and recently people found them in South America. I also read that companies had to order at least 10,000 units, so would that mean 10,000 per region, or 10,000 in total? Because either way, that's a LOT of them out there, and certainly aren't worth $2,000 complete.

It's a shame, because it's a really good game. The only way you can play this on real hardware at an affordable price would be either buying a bootlegged cart, burning this onto an MMC3 cart, or buying a PowerPak.
