*Back to the Future Part II & III is a 1990 video game for the Nintendo Entertainment System based on the second and third films in the Back to the Future trilogy. The game was produced by Beam Software and published by Acclaim Entertainment under their LJN label.
Stan Stepanic of Gamefreaks365.com gave Back to the Future II & III positive remarks in regards to similarities with The Goonies II, but gave it a largely negative review due to the lack of a password or save feature coupled with its notorious length, although there was a code to skip to the second half of the game. Stan stated that it took him roughly six hours just to map it, and he spent so much time trying to finish it he actually turned it off out of boredom.
