People aren't mad at the trailer for the subject matter inside of it. I doubt many people even grasp the depth to look inside of what was shown and question what they're seeing and why they're seeing it.
All they care about is how a dad hug with his child lasted for over a minute, and there was no release date at the end, even though there was a pre-order prompt. In the internet's case, that's an epic fail. But, this is what happens when the internet is impatient, and frankly, 90% stupid.
I'd much rather Square take their time with this game instead of rush it just to get it out to appease people, only to turn it into the next Assassin's Creed Unity. I can't be the only one that wants this game to be good. And the most important thing is not releasing it in a timely matter to appease you. The most important thing is to release it when it's good and ready.
It is tiring. But I don't get why the lack of female playable character is such a big deal. FFX-2 was an estrogen frenzy. Where was the talk of playable male characters? Nobody really gave a crap. But fast forward over ten years later, and everybody makes a fuss because the lack of boobs makes the game less appealing.
And I find it kind of disheartening that I HAVE to clarify that not everybody thinks that way, but the majority of people DO. Sex sells, and the best way to do that is to have attractive females in your games. It's why practically every game does it. And I do kind of give SE SOME credit for going against that grain with XV.
Not that I'm saying I wouldn't mind more female characters. But I'm not one of those people that thinks it's a crime that there aren't any. It's not something I consider important for a game. The important element to a game is its story. And if someone needs more playable females in the story for it to be good, well, I think they need to re-examine their priorities in what they find a story 'good'.
