Howard Scott Warshaw the creator of E.T. the Extra-Terrestrial Atari video game and accused of bringing down Atari because of it.

Life Unedited (Nothing Is Taboo)

In 1981, Warshaw went to work for Atari after an short unchallenging time at Hewlett-Packard. His first success, Yars' Revenge, became extremely popular and is still regarded as one of the best games made for the Atari 2600. This led Warshaw to be picked as the designer of the game adaptation of the film Raiders of the Lost Ark, which was also a commercial success and was critically acclaimed at the time.
It was his success on Raiders that led to Warshaw being chosen to design and program the ill-fated Atari 2600 adaptation of E.T. the Extra-Terrestrial. Problems began early as he was only given five weeks to go from concept to finished product. Warshaw was assisted by Jerome Domurat, a graphics designer at Atari. Although the game was finished on time, it was poorly received and seen as being confusing and frustrating. Atari took a major financial loss on the project which, combined with other poor business decisions and conditions, led to the company being divided and sold within two years. During this time, Warshaw developed and almost finished another game called Saboteur. He left the company before it was completed. It was then re-adapted into a game based on the television series The A-Team but this also remained unfinished. Atari was dismantled before either version could be released.
In the 2014 movie, The Rise and Fall of Atari, Warshaw is quoted as saying that all his games sold over 1 million copies.
