Grandia (video game)
In March 1999, Game Art's Japanese publisher ESP Software showcased a PlayStation version of "Grandia" at that year's Tokyo Game Show expo, along with confirmation that the game would be released in English for the first time in North America by Sony Computer Entertainment America. Working Designs, which had previously worked with Game Arts on bringing their "Lunar" games to the region, had expressed interest in publishing the game, but were ultimately unable to secure the rights. New features for the PlayStation version included support for the system's DualShock analog control sticks and vibration function, as well as compatibility with Sony's Japanese-only PocketStation peripheral, which allows players to download game data on a portable device for use in a special mini-game. Although the company had expressed interest in bringing the game to the PlayStation as early as 1998, technical problems originally prevented the title from being ported to the system. Game Arts was later able to release the game with a slight loss in frame rate and a marginal decrease in video effects the following June. The North American version was originally announced by Sony as a summer release during the 1999 Electronic Entertainment Expo in Los Angeles, but was pushed back to the following October. "Grandia" was later released for the PlayStation in Europe in 2000 by Ubisoft.
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.
