Galge

A bishōjo game (Japanese: 美少女ゲーム, Hepburn: bishōjo gēmu; lit. "pretty girl game") or gal game (ギャルゲーム, gyaru gēmu; often shortened to "galge") is "a type of Japanese video game centered on interactions with attractive girls". Bishōjo games are similar to Choose Your Own Adventure books in the way of narrative, in which the game tells a story, but the player may make choices to change how the story flows.
