It was also the first to have recognizably modern anime-style artwork: its characters had very large eyes and a tiny nose and mouth but were otherwise basically normally proportioned, characteristics which today are found in virtually all bishōjo games.
Prior to 1985, girls were generally drawn either as normally proportioned adults or super deformed children.
The Star Ocean series of RPGs also feature dating sim elements in a similar manner.
Some Japanese dating sims may allow the player to have romantic or sexual relationships with characters in their teens.
Dating sims such as Tokimeki Memorial often revolve almost entirely around relationship-building, usually featuring complex character interactions and branching dialogue trees, and often presenting the player's possible responses word-for-word as the player character would say them.
Dating sims such as Tokimeki Memorial, and some role-playing games with similar relationship based mechanics to the genre such as Persona, often give choices that have a different number of associated "mood points" which influence a player character's relationship and future conversations with a non-player character.
Some games involved elements of force and brutality.
These came to national attention in Japan in 1986 with the release by d B-soft of 177, a game where the player takes the role of a rapist.
Because of this, Eroge companies make a censored all-ages (15 ) version of the PC version for various consoles.These games often feature a day-night cycle with a time scheduling system that provides context and relevance to character interactions, allowing players to choose when and if to interact with certain characters, which in turn influences their responses during later conversations.While bishōjo games make up the bulk of dating sims, other types of games exist.(The game's title originates from the number of the Japanese law criminalizing rape.) 177 was not actually the first game designed around this premise, but it was unusually explicit.The game caused debate in the Japanese parliament and was eventually recalled and re-released with the most controversial scenes removed.
