Jinkō Shōjo 2 (人工少女 2, lit. "Artificial Girl 2") is a 3D erotic life simulation game developed by Illusion for the PC. The player assumes the role of a young male on an island, populated with a number of idyllic locations typical to the genre (such as the beach, a hot spring, a school, a lab/office, a train car, and a castle's church and dungeon.) Accompanying the player is a cute girl, who provides a number of different social and increasingly erotic actions for the player.
At the beginning of the game, the player may customize the girl's different attributes, such as her hair color, hair style, breast size, skin color, and blood type (this has the added function of selecting her personality, based on the popular Japanese pseudoscience). Unless third-party modifications are used, the girl will still more or less look the same underneath the hair and minor modifications, a problem foreseen by most gamers to plague many other games of this genre that attempt this type of customization. This (along with other concerns, see below) has led to a lot of the aforementioned "modding" to this game, both inside and outside of Japan.
Third party modifications and patches
Since Jinkō Shōjo 2 has gained so much popularity among the adult gaming community, many unofficial mods and patches have been made for it. The typical patches include patches that convert the Japanese text into English, that enable Alt-Tabbing in and out of the game, that unlock all the girl's costumes, that fill the girl's love meter, and that disables her showering after every H-scene.
The majority of these fan made mods affect the appearance of both the girl and her clothing. Some mods edit the girl's physical features, changing her skin color, height, slimness, and even shape, color, and size of her eyes and lips. The other mods mainly create new costumes for the girl to wear. These can range anywhere from real-life based outfits to outfits from famous anime, manga, and games.
