It seems like you have to offer your soul for the kizuna game. Thanks.
Well, to be honest, it just seems to most here that you are delightfully aloof (at least thats how you come off).
The thing with Euro copies of Kizuna is that it was a recalled release that was stripped of it's euro paperwork only leaving a few (known) handfulls of copies throughout the world.
When it was last sold on the open market a few years back prices were in the low to high teens with a median sale price of $15,000 depending on condition and who the available buyers were at that time (a key thing to consider with a title like this).
The very last sale we know of was when fellow forum member Wolf offered Shawn (the forum owner and administrator here) $55,000 for his copies of Kizuna and Ultimate Eleven.
That sale is more of a special circumstance and would not have a DIRECT influence on the overall market value of the title, however, it does have an indirect effect on it and only add's to both the perception and reality of Kizuna's rarity, desirebility and value.
If you were seriously out to find a copy of this game (authentic, complete and preferably in collectors condition of eccelent or better) then you would want to have AT LEAST $15,000 to $25,000 ($20,000 median) cash ready, on hand.....if not more ($30,000 to $35,000 on an extreme high depending who the available, potential buyers are at the time the cart becomes available).
