personally, I don't think you can use any one method of finding games to justify a game as being 'the rarest'.

I'haven't quoted everything you say, but you're right. Nowadays all collectors (or most of us) use ebay as reference to say wheter a game is rare or not, when we shouldn't do it because the true rarity is determined by things like how many games were released and how many are in hands of people who would sell them. But we don't and games wich perhaps are not rare are sold as if they were gold.
I'll try to explain why i think the spanish market is so special.
The main reason why i think its special its because there's a lot of missinformation about it. I don't know anyone from Spain who is sure if certain games were released or not here. This is due to the bad job that SPACO and the other companies which sold nes games did while they sold nes games in Spain, because if they had done it the way it was meant i'm sure that the magazines would have reviewed some games i've seen for sale in spain like tmnt tournament fighters or darkwing duck (i know those copies were for the spanish market because they had a sticker wich said "spanish instruction booklet inside") wich were directly imported from germany.
This problem of missinformation becomes bigger in the years before 1991 because there are games wich come with a bilingual instruction booklet (german/spanish) and a english box (mainly are games from Sunsoft, Taito, Capcom and Konami) and there are others wich come with the "original seal of quality" transtaled into spanish as you can see here:

this translation into spanish of the seal can be also found in other "small boxes" or in the zapper box (and i guess in other accesories boxes).
The other reason why i said it was special its because the "mentality" of the spanish people wich seems it's quite different from people from other countries. It seems that the 90% of spanish people think that the things they don't need anymore are worthless so they throw them to the rubbish. And this unfortunately happens too with nes games

Sometime ago the other guy i mentioned before told me that a friend of his brother threw about 20 CIB nes games to the rubbish

And thats the reason why there are few games for sale at ebay.es in comparison to other ebays.
One could say that this low offer is the reason why nes games listed on ebay.es are so expensive but i don't think so because there are many sellers who are reselling games they bought at flea markets, at second hand stores or even at other ebays at a "gold price", and some even overbid themselves (anacurdo is one of those)
This things makes difficult for any spanish collectors to find games at a good price and in good shape.
Well, that's why i said the spanish market is special. I'm not sure if i've explained it as i should but there are so many things to talk about it that i guess i'd never stop talking about it

About defenders of dinatron city i can say it was reviewed in Hobby consolas (one of the most important videogames magazine at that time) and they always stated (hobby consolas) that they only reviewed games wich were officially sold in Spain and that's why spanish people say it was released in Spain. I don't know what to think about it, but i've never seen it for sale anywhere in spain so perhaps it wasn't released... but this doesn't mean anything because at that time i was only 12.
