I have that, addams family and lemmings sealed. I may have a couple more, but I don't think so. They were bought a long time ago when stores still sold nes stuff, weren't bought as collectors items. I just never opened them.
Eyyyy I could've bought that too. My KB had tons of these sealed (along with another NES game) up until 1999 or so, but they were charging $20 (which was too much, and I wasn't thinking).
I bought that game for $5 at Wal Mart just before going to college back in 96. I didn't keep it sealed long though, it was worth it to open it and play for $5.
I picked up a Star Tropics 2 sealed also at a Toys R Us in about 2001. It was only like $3 so I figured I would keep it sealed. Also a couple of years ago I found a sealed Battletoads at a pawn shop in Wyoming and I was like "sweet!". I already have both so I will keep them sealed and mint as the day they were manufactured. I would kind of like to have a sealed game from each Nintendo system.
