A virtual dating game
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.
Eroge only gets released to PC because large Japanese game companies do not want to release games with sexual content on their game consoles.
Because of this, Eroge companies make a censored all-ages (15 ) version of the PC version for various consoles.
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.
The technical definition of a dating simulation game, known as a romantic simulation game in Japan, can involve several technical elements such as a time limit, several statistics such as looks and charm which can be boosted through exercise, or an "attraction meter" which can increase or decrease depending on one's decisions.
