In a article in Time Magazine , On-Line reported that they were making a version of the game for straight women, though this never materialized. That same year, Koei released another erotic title, Danchi Tsuma no Yuwaku Seduction of the Condominium Wife ,  which was an early role-playing   adventure game with colour graphics, owing to the eight-color palette of the NEC PC computer. It became a hit, helping Koei become a major software company.
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. The re-released version of Custer's Revenge was titled Westward Ho! X-man features the player as a nude man working through a maze toward a pink door in the center, past antagonistic crabs, teeth and scissors. Players that reached the pink door were rewarded with a controllable sex scene. Like with Koei, several other now-famous Japanese companies such as Enix , Square and Nihon Falcom also released erotic adult games for the PC computer in the early s before they became mainstream.
Early eroge usually had simplistic stories and extreme sexual content, such as rape. These factors often led to widespread condemnation from the Japanese media. Soon, new genres were invented. In , a company called Entertainment Enterprises, Ltd. The game requires the player to drive through the city maze gathering dots like Pac-Man before reaching a brothel where the player is required to fight off venereal disease and collect keys to unlock sex scenes.
Once the scenes are unlocked the top door is open where the player can go and engage in a controllable sex scene letting the player have intercourse with a woman until the player reaches orgasm and the game is over.
Also released in was Strip Poker: The same company would later release the controversial Vixen , featuring another page 3 model Corinne Russell. Both pre-rendered and real-time 3D graphics were also used. While most games could be considered nothing more than pornography , some attempted to include actual story and plot. This can be seen in some games with less explicit content, equal to an R or PG rated movie.
The game derived gameplay elements off an older title called Qix , which didn't have sexual images. The object of the games is to slowly remove pieces of the playing field while avoiding an enemy or groups of enemies. Removing the playing field slowly reveals pictures of models in escalating states of undress. The game had nine sequels throughout the s with a final game in In it, before any eroticism, the user has to first win the affection of one of a number of female characters, making the story into an interactive romance novel.
Thus, the love simulation genre was invented. Soon afterwards, the video game Otogirisou on the Super Famicom attracted the attention of many Japanese gamers. Otogirisou was a standard adventure game but had multiple endings. This concept was called a "sound novel. Their next game, Kizuato , was almost as dark.
However, in , they released To Heart , a sweetly sentimental story of high school love. After a similar game by Tactics , One: Kagayaku Kisetsu e , became a hit in , Visual Art's scouted main creative staff of One to form a new brand under them, which became Key. It contains about 7 brief erotic scenes in a sentimental story the size of a long novel an all-ages version was also released afterward.
Kanon sold over , copies. Although many eroge still market themselves primarily on sex, eroge that focus on story are now a major established part of Japanese otaku culture. Please update this article to reflect recent events or newly available information.
October Modern console publishers often have policies against depictions of nudity and explicit sexuality, particularly Sony Computer Entertainment with its PlayStation brand of consoles. Examples include Red Light Center , Singles: Flirt Up Your Life and Playboy: While it is not explicitly intended for purely adult-oriented entertainment, the virtual world of Second Life , which is made up almost entirely of player-made content, has an array of very exotic adult entertainment including nudity and full-on sexual activities.
Adult games may take the form of bootlegs , circumventing mainstream publishers who may have policies against such games. Patches or hacks to mainstream non-adult games may add sexual and pornographic themes, mostly for humor , especially when sexuality was never intended in the original game.
Oblivion and The Elder Scrolls V: The Internet has allowed adult games to receive wider availability and recognition, including amateur games in Flash or Java. It has also allowed amateurs to create and distribute adult text adventure games, known as "Adult Interactive Fiction" or AIF.
