Rarest console fighting videogame

The rarest fighting game for a home console is the European PAL version of SNK’s Kizuna Encounter on the Neo-Geo. It is uncertain whether the game was ever actually released in the PAL territories and only five copies of this version of the game cartridge are known to exist. If you are lucky enough to find one, a cartridge can fetch up to $12,500 (£7,740). Copies of the NTSC version are both cheaper and in more plentiful supply.
