What's the rarest NES game you own?

In Collecting

According to any guide or collaboration of guides.

Mine would be my . It's a futuristic racing game by Activision. I have seen it listed as a B+ or A- rarity.

I also have game and box, but no manual.

I don't actually "collect" any more, so those will probably remain the rarest of my NES Games.

I sold most of my 100+ games a couple years ago like an asshole. Out of the remaining, I guess complete M.C. Kids is about all I have. And Karnov, of course.

I guess my rarest would be this gold cart that I have. No idea what it is really, just says "NWC" on it.

I wish.
