Maniac Mansion
After Warner Communications sold the company, he joined National Semiconductor. In 1984 Crockford joined Lucasfilm, and later Paramount Pictures. He became known on video game oriented listservs in the early 1990s after he posted his memoir "The Expurgation of Maniac Mansion" to a videogaming bulletin board. The memoir documented his efforts to censor the computer game "Maniac Mansion" to Nintendo's satisfaction so that they could release it as a cartridge, and Crockford's mounting frustrations as Nintendo's demands became more obscure and confusing.
