Based very loosely off the 1985 film "The Goonies", this game is among the most unique titles offered by the NES. It managed to help define a genre back in the day-- the side-scrolling free-form adventure. This game has no defined "stages" and no "bosses", as expected from the traditional side-scrolling formula, but rather allows you to go anywhere and see anything-- provided, that is, you have found the tools necessary to reach that area. It is very reminiscent of Nintendo's "Metroid" series in that regard. Later effort "Castlevania: Symphony of the Night", also by Konami, would bring this genre to its current level of perfection. I am surprised that such an original style of game, that is, this kind of adventure, is not more frequently imitated. But in any event, I suppose it is best to enjoy what we have in "Goonies II"-- if you can find it.
