Eroge

An eroge (エロゲー) is a Japanese video or computer game that features erotic content, usually in the form of anime-style artwork.

Types of eroge
Most eroge are visual novels or romance sims. However, there are many other kinds of eroge:
 * Conditioning game, in which the female character, by performing different types of sexual activities, changes her stats, unlocking additional types of play.
 * "Strip"' versions of traditional games, including but not limited to mahjong, pachinko, poker, chess, and blackjack. Many adult arcade games fall under this category.
 * Interactive video, which is essentially nothing more than an eroge that plays in a DVD player (also known as DVDPG, DVD player game).
 * Sex simulators, often in 3D.
 * Puzzle games with erotic background images.
 * Ero-cha is online sex chat employing full voice chat with voice actresses in real time. This system uses 2D eroge-type characters, as well as erotic game style point-and-click functions.
 * Other common video game genres, such as RPGs and beat-em-ups, with erotic elements.

Eroge may be bishōjo games, otome games, or BL games, although bishōjo games are the most popular. A small number of bara eroge have been produced, mostly dōjin soft.
