According to some sources, this game was supposedly never released in the U.K. The only 'Pal' version of the game to exist is really the Australian version, not the U.K. version. That is why it is so rare and the 'Pal' English version is currently worth around 80 pounds on ebay.
However, strangely enough, the game was released in other countries in Europe like Italy, Germany and Spain so those versions are more common.
