Eroge

An eroge (エロゲ or エロゲー, erogē; pronounced [e̞ɾó̞ɡe̞(ː)]), also called an H-game, is a Japanese genre of erotic video game.

[3] That same year, Koei released the erotic title, Seduction of the Condominium Wife (団地妻の誘惑, Danchi Zuma no Yūwaku), which was an early role-playing adventure game with color graphics,[4][5] owing to the eight-color palette of the PC-8001 computer.

[7] Some writers say that Yakyūken produced for Sharp MZ computers by Hudson Soft is the first Japanese adult game.

[8][9] Other now-famous Japanese companies such as Enix, Square and Nihon Falcom also released erotic adult games for the PC-8801 computer in the early 1980s before they became mainstream.

[10] Early eroge usually had simple stories, some even involving anal sex, which often led to widespread condemnation from the Japanese media.

Soon, new genres were invented: ASCII's Chaos Angels, a role-playing-based eroge, inspired Dragon Knight by Elf and Rance by AliceSoft.

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.

[11] After a similar game by Tactics, One: Kagayaku Kisetsu e, became a hit in 1998, Visual Arts 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.

[13] There is no set definition for the gameplay of eroge, except that they all include explicit erotic or sexual content depending on the game.

Additionally, some games may receive an "all-ages" version, such as a port to consoles or handheld devices where pornographic content is not allowed, which either remove or censor the sex scenes entirely.
