Dating and simulation games
When the game ends, the player either loses the game if he failed to properly win over any of the girls, or "finishes" one of the girls, often by having sex with her, marrying her (as in Magical Date), and/or achieving eternal love.
This gives the games more replay value, since the player can focus on a different girl each time, trying to get a different ending.
One game series that often includes dating, with the goal of marriage, is the farming sim series Harvest Moon.
The subplot of dating is more focused towards choosing one of several girls or guys (dependent on the player character's gender) and offering them presents or joining them on events in the game.
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.
The term "dating sim" is also often used incorrectly in English as a generic term for romance-driven games (ren'ai games), a subject matter which is stereotypically associated with the visual novel genre.
Our World is one of their more popular simulation games, hosting over 75 million players who mingle in a virtual reality.
Or — if you’re more into fantasy games — you can play Knights and Brides and duel other players online.
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.
