Finding that perfect balance between gameplay and story in a horror game can be extremely difficult. If someone's jumping into an FPS or third-person action game, for example, they would probably expect to be spending more time gunning down enemies than watching cutscenes. In contrast, horror games need to gradually reveal their story over the course of a playthrough to keep players engaged, while also making them feel like a part of the experience through the gameplay itself, since this is a video game after all, and not a movie.
