Most eroge games, a fairly large library, found its way on the NEC PC-98 platform.
FM Towns also received many games, more so than Sharp X68000 or MS-DOS, whilst the MSX platform (which had many eroge games in the 1980s) was nearing the end of its lifetime by now.
To Heart's music was so popular it was added to karaoke machines throughout Japan—a first for eroge.
After a similar game by Tactics, One: Kagayaku Kisetsu e, became a hit in 1998, Visual Art's scouted main creative staff of One to form a new brand under them, which became Key. It contains only about seven brief erotic scenes in a sentimental story the size of a long novel (an all-ages version was also released afterward), but the enthusiasm of the response was unprecedented, and Kanon sold over 300,000 copies.
Usually the sexual content is presented as a reward for the player's successful fulfillment of certain tasks.
Like other pornographic media in Japan, erotic scenes feature censorship of genitalia, only becoming uncensored if the game is licensed and released outside Japan, unless produced illegally by doujin (usually with a construction kit like NScripter or RPG Maker).
Games also started to appear on Windows as it grew in popularity. 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. 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. In 1996, the new software publisher Leaf expanded on this idea, calling it a visual novel and releasing their first successful game, Shizuku, a horror story starring a rapist high school student, with very highly reviewed writing and music. However, in 1997, they released To Heart, a sweetly sentimental story of high school love that became one of the most famous and trendsetting eroge ever.
Eroge was much less common on consoles - only NEC's PC Engine series had officially licensed adult games, and from the mid-90s, Sega's Saturn.
Both Nintendo and Sony disallowed adult video games on their consoles.
Although many eroge still market themselves primarily on sex, eroge that focus on story are now a major established part of Japanese otaku culture.
Oftentimes, voice actors who have voiced for eroge have been credited under a pseudonym.
As with yaoi manga, the major market is assumed to be female.
