If you're into video games, you're probably aware of the white whales. Earthbound for the Super Nintendo, Stadium Events for the NES, that impossible-to-find Nintendo World Championship cartridge that sold for $US100,000 ($133,804) on eBay a couple years ago despite a torn label.
All of those make sense. They're either great games or carry enough historical baggage to ascend towards untouchable Honus Wagner status. But video game collecting is a weird hobby in the sense that legacy doesn't always matter. If you collected baseball cards, you'd never find yourself dropping a ton of cash on, like, a Cameron Maybin rookie card. It's Cameron Maybin. A totally average player with a totally average career. But with games, sometimes a replacement-level product can demand a ton of money.
