Very interesting -- I see your point. It's to help establish "100% genuine accuracy". However, what if you buy something on eBay and the previous owner swapped the plastic insert out with a jewel case, or vice versa? Also, you aren't mentioning which games came with "Turbo Gear" advertisements and stuff like that, which would be very important. To be sure, I think you'll need to purchase your games new/shrink-wrapped. Otherwise, unscrupulous sellers could pull a bait-and-switch with the insides.
