Answer: Maniac Mansion

Maniac Mansion was a popular 1980s graphic adventure game published by Lucasfilm Games for the Commodore 64 and Apple II. It marked the first venture into game publishing for Lucasfilm and was a runaway hit, ultimately getting ported to the NES. The game received positive reviews and was frequently lauded for its well developed plot and film-like qualities.

Given the praise heaped upon the game and its origins within the Lucasfilm publishing house, it was no surprise when a spin-off television show was pitched based on the game. Produced in Canada but aired in both Canada and the United States, Manic Mansion the television show was loosely based on the characters and setting of the Manic Mansion game. The show was well received as a sci-fi/family sitcom—fans of the original game can only imagine how far the black humor of the original game had to be toned down to pass as a family show—and aired from 1990-1993 with a total of 66 half-hour shows.
