Grandia (video game)
Grandia is a role-playing video game, developed by Game Arts and published by ESP Software for the Sega Saturn console as the first game in their "Grandia" series. Released in Japan in 1997, the game was ported to the PlayStation in 1999, with an English version of the game appearing on the platform in North America in the following September by Sony Computer Entertainment, and in Europe in 2000 by Ubi Soft. The game was produced by much of the same staff who worked on the company's previous role-playing endeavor, the "Lunar" series, including producer Yoichi Miyagi and composer Noriyuki Iwadare.
Adventure game
Due to a lack of content restrictions, some of Japan's earliest adventure games were also bishoujo games with "eroge" content. In 1982, Koei released "Night Life", the first commercial erotic computer game. It was a graphic adventure, with sexually explicit images. That same year, they released another "eroge" title, "Danchi Tsuma no Yuwaku" ("Seduction of the Condominium Wife"), which was an early adventure game with color graphics, owing to the eight-color palette of the NEC PC-8001 computer, and role-playing video game elements. It became a hit, helping Koei become a major software company. Other now-famous companies such as Enix, Square and Nihon Falcom also produced similar "eroge" in the early 1980s before they became famous for their mainstream role-playing games. In some of their early "eroge", the adult content is meaningfully integrated into a thoughtful and mature storyline, though others often used it as a flimsy excuse for pornography.
