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.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 the two genres often share a common visual presentation, dating sims are sometimes considered to be more statistically based than the "choose your own adventure" style of visual novels.
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.
The game lasts for a fixed period of game time, such as one month or three years.
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.
Sexually explicit dating sims may fall into the category of H Game or Eroge.
Eroge only gets released to PC because large Japanese game companies do not want to release games with sexual content on their game consoles.Some original-English dating sims include Sim Girls, In a typical dating sim, the player controls a male avatar surrounded by female characters.The gameplay involves conversing with a selection of girls, attempting to increase their internal "love meter" through correct choices of dialogue.Predominantly hentai-based, each eroge title brings you on a unique adventure with an erotic twist.From turn-based strategy and tower defense to clickers and RPGs, all games have a porn element added to them.This gives the games more replay value, since the player can focus on a different girl each time, trying to get a different ending.
