E.T. the Extra-Terrestrial

Atari's December 1982 tie-in was developed in just five weeks, which is 75% faster than the average 20-week development cycle for a typical action game of that era. The resulting game was so incomprehensible and unsellable that millions of cartridges were buried in a New Mexico landfill, symbolizing the 1983 video game crash. Its 3.5 million unsold units, buried 30 feet deep, exceeded the total production run of many contemporary hits like Pac-Man.
