A Japanese company is working on a video game adaptation of the movie "The Sound of Music". It is a hybrid. It starts with a musical section teaching the Von Trapps to sing, then switches to a dating sim between Mr. Von Trapp and Sister Maria and finally turns into a first person shooter where you have to kill Nazis to escape from Austria. There is also supposedly a secret section that can be unlocked involving hard-care incest, but that is only intended for the Japanese market.
