It is very difficult to determine that sort of thing, nobody knows exactly how many of what exist and how many survived. What I do know though, is that I have never been offered a Gauntlet for sale, nor have I seen one sold (zip it Marco, I don't care about unlabled carts ). I also do not consider Xante or Beagle Bros. carts rarity 10's. It is a very gray area, since there is not that many people around, insane enough to drop the kind of money needed to aquire rarity 10's. Another reason why I want to know from little Saikyo what he bases his choice on, I bet he has never even seen a rarity 10 cart up close.
That is right I have never actually SEEN a rarity 10 cart (though I'd like to)
I also agree that Xante and Beagle Bros. carts shouldn't be that rare.
Beagle Bros. carts are (allegedly) pirates and Xante carts were made almost everyday
from people who visited the shops and had the carts made.
The reason I chose these games is based on a lot of info from various sources.
First off Air Raid hardly any of these have been found and I do beleive that
less than 40 were made (not 20 dont ask me why i chose 40 just an estimate). BTW I know that this is a pirate also but its a unique game.
Pepsi Invaders is self explanatory Only 125 were made and were not for sale
at all, only those lucky coca cola guys got these. Probably loads got thrown
out as not everyone is interestd in video games so maybe a little over 50
have survived.
Eli's Ladder and Video Life, well Im not too sure about these However I think that 200
of each were probably made but how many have survived is another question.
These games are just rough guesses.
I know im probably wrong in all aspects of my list but still.
