Cart vs cartridge: from as long as I can remember, they were referred to as carts. If we want to get technical, shouldn't they be referred to as game paks? Yup, that's sort of my point. Since the mass uses the term cart, I wouldn't personally want to see anything else on the package.
Pedigree: I think pedigree status shouldn't be passed out willy Nilly. With that said, about 60 - 80% of my personal collection has been gotten from a local guy that has a storehouse of games, likely he had a toy/game store years back, or was a distributor. I think the stuff gotten from him definitely would deserve pedigree status, considering the high quality and quantity of items, as well as the backstory, which remains unknown in its entirety at this point. On the other hand, Joe schmoes collection, nah, not worth having a pedigree. Gotta be significant for that status
