Are these actual videos you're quoting? Because I don't recall any of those. And fyi while Hitler was a scumbag, it's impossible to deny that he did amazing things for Germany prior to committing terrible atrocities.
In a way I'm envious of your ability -- and apparent need -- to suspend disbelief. Being able to believe that some stories exist in a vacuum would probably limit the emotional trauma I get from reading books or whatever. But then, what's the point, otherwise? I know Tolkien strongly denied the claim but it's hard to see how The Lord of the Rings could not be, in some parts, an allegory for World War II. And smurf, that's incredibly interesting and I get a lot of joy from seeing connections, even if they're entirely false.
I've learnt a lot from games. I still maintain that the only reason I passed school was because of video games and the skills they taught me. And in keeping with that, Game Theory has taught me a lot of cool trout too. The Assassin's Creed video about genetic memory and how we're all walking talking usb sticks was smurfing incredible and something I would have never known if it hadn't been loosely connected to a video game. I just... I don't understand your feelings towards it. If you were just like "eh I don't care so much" or "I hate his voice" then maybe I could get it. But as it stands, you seem anti-fun and anti-learning -- living in a bubble is not beneficial.
I assume like most story lovers, you too have dreams of telling your own one day. If so, I challenge you to make sure that none of the characters have traits that you've seen in your friends or family. I challenge you to make sure none of the conflicts they encounter are ones that you've had or your friends have had in life. Man, I just, life is full of metaphors and symbols and references. How do you believe that any story is created without influence from something else, especially the real world?
Did you know Aerith's death was probably inspired by the passing of Hironobu Sakaguchi's mother? I hope hearing this theory didn't scar you or ruin your appreciation for the game.
