Christianh:
This is a fact :)
Yes, but there is a lot of work to be done to establish if this is
justified.
Christianh:
I don't understand why the Tintin store in London would not sell the game.
Because they don't carry all varieties of Tintin merchandise by any stretch of the imagination - they are a tiny shop, and very selective in the lines they have. Experience shows that items which would be outside of their expertise to promote tend to take a back-seat - they don't have any way of demonstrating a game, such as screens. It's also not a place that someone would go looking for a game, so it seems unlikely that they would be the sole outlet for a product (I've not said that they wouldn't have had copies, or have sold some).
Christianh:
The rumour I have heard is that it was only sold in that store before it was withdrawn from the shelves.
Indeed, that is certainly the rumour being put about, but what I'm looking for is corroboration of the rumour - the high prices commanded depend on the rumour being true, and the rumour is being promoted on sites like eBay to justify the high price being asked, and so far it just seems to be a circular route of the rumour feeding the prices and the prices shoring up the rumour. If we find out that 200 copies were sold, what then? What if it was 2,000 copies? All have an effect.
Christianh:
But I'm not really after a debate on the Tintin store.
No, neither am I, but the points of Tintinological interest (which is why we are here) are, is it really rare, and are the high prices justified? The rarity/ value of the thing hinges on the Tintin Shop having been the exclusive outlet, and having sold few copies - that will inform the price/ value of the copies available, and may be indicative of the valuation of the promo disc you have.
We've seen speculators make hay from the "rarity" of books and items which are actually fairly common (e.g. mint Methuen first edition copies of
The Shooting Star, which actually come from cases of the books discovered in a warehouse - a considerable number have sold at very high prices as being "rare", but without regard to the fact that there are now more on the market than ever before).
Promo discs get sent to retailers and reviewers, of whom there are probably more than twenty; the label on the disk is obviously a factory printing, again suggesting that a quantity greater than twenty was made to send out to the press, etc.
Were the "twenty copies" sold of the retail disk story shown to be true, it could mean that there are
more promo discs out there than retail, and it would (one assumes) be worth less.
