No one was able to provide a satisfactory answer in the previous threads, so I shall ask once more: What does the porn add to this game? Why couldn't this have just been a waifu game without porn?
Answers that are not acceptable or are invalid:
>"japanese developer" (fails to explain what the porn adds to the game)
>"sex is human" (fails to explain what the porn adds to the game)
>"how can you take history seriously without sex?" (answering a question with a question is not acceptable)
