The inclusion of sex and nudity in video games has been a controversial topic since the early days of the industry.
One of the earliest video games (if not the first) to feature sexual themes was the 1981 text-based Softporn Adventure, published by On-Line Systems for the Apple II.
Despite heavy piracy the game still sold 25,000 copies, roughly equivalent to 25% of the number of Apple II's sold at the time.
In a 1981 article in Time Magazine, On-Line reported that they were making a version of the game for straight women, though this never materialized.
In 1982, Japan's Koei, founded by husband-and-wife team Yoichi and Keiko Erikawa (and later known for strategy video games), released the first erotic computer game with sexually explicit graphics, Night Life, Also in 1982, the video game company Mystique released three unlicensed games for the Atari 2600; Beat 'Em & Eat 'Em, Custer's Revenge, and Bachelor Party.
The games were noted for their negative reception, particularly Custer's Revenge for its depiction of (what was perceived as) General Custer raping Native American women.
Despite the increased sales (due to one of the first instances of video game controversy), Mystique went out of business after only releasing these three games.A company named Playaround began distributing these games packaged in 2-in-1 "double-ender" cartridges.These games also included re-worked versions with female protagonists, Philly Flasher (Beat 'Em & Eat 'Em), Bachelorette Party (Bachelor Party), and General Retreat (Custer's Revenge).The re-released version of Custer's Revenge was titled Westward Ho!, and featured slight modifications, such as the Native American woman beckoning to indicate that she welcomed Custer's advances.They released four new titles, Burning Desire/Jungle Fever and Cathouse Blues/Gigolo.
