An adventure where choices actually impact the story.

Either prominently containing or entirely themed around romance, this genre is typically focused on interpersonal romantic relationships between characters and the player.

Focused on using its text, moreso than its visuals or audio, to tell the bulk of its story/plot. (Still can have great audio and visuals, though!)
