According to "Retro Gamer"s John Szczepaniak, the first stealth game was "Manbiki Shounen" ("Shoplifting Boy"), published in November 1979. The PET 2001 personal computer game was developed by Hiroshi Suzuki and involves a boy entering a convenience store and attempting to shoplift by stealing "$" symbols while avoiding the line-of-sight detection of the owner. If caught, the player is led away by the police. Suzuki presented the game to developer Taito, which used it as inspiration for their similar stealth arcade game, "Lupin III" (based on the manga and anime of the same name), released in April 1980. In November 1980, Suzuki developed a sequel, "Manbiki Shoujo" ("Shoplifting Girl").
