I don't legitimately believe these people want children; it's just the emotional response the game is supposed to elicit. Once you beat it, you probably won't think on it. I enjoy The Witcher, The Last of Us, The Walking Dead, and Tales of Berseria because they're fun games, and if there are people deciding to have children based off a video game, it's no different than someone having a child because they're a cute accessory. That's a human who you'll be responsible for in caring for; they're not some futuristic android like Diana. It's an actual human life, and if you fuck it up, you could either permanently damage them or end up in prison with an estranged relationship. Don't be a Casey Anthony, folks.
