While bishōjo games make up the bulk of dating sims, other types of games exist.
Games where the player character is female and potential objects of affection are male are known as Gx B or otome 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.
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.
