The game lasts for a fixed period of game time, such as one month or three years. 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. In a typical dating sim, the player controls a male avatar surrounded by female characters. 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.
