Here is the Kizuna Story:
1.) Kizuna was delivered to SNK London in 1996 and SNK London send copys of them to Maro (official NeoGeo Partner for Germany) in Stuttgart.
2.) In China a big ROM Manufacture burn in flames and ROM-Chips getting rare and Prices for ROM-Chips grow. (approved by Mr. Hosoya)
3.) SNK Osaka need ROM for their new MVS Releases and ordered all games back to Japan. Because the have more profit in MVS than in AES
4.) SNK London send all Kizuna back to Japan, but only 1 order was delivered in Europe and this was to Maro in Stuttgart.
5.) This all happens in very short time
6.) Maro only sell a few Kizuna Encounter in 1996, because people give their hard earned money for Real Bout and Metal Slug, not for Kizuna.
7.) This is reason, almost most of the Kizuna come from Germany. And in Germany only a few Kizuna sold. And this are since today up to 6 Pieces!!
8.) Today there are more Kizuna in Germany, but not many... (I think not more than 10)
People how collect NeoGeo games in 1996, have today family and dont interested in this hobby anymore and dont know what they have in a tiny box in their attics.
9.) The owner of Kizuna #6 dont know about its rarity. A friend of him read about the rarity of Kizuna and than both began search in internet and ask in Planet-SNK forums about this game an post some pics and more of it... And this version is a real one!! No Fake!!!
And he have some more rare games from this time, like Metal Slug, and dont know how many money this is today...
