What trailer did you watch? I have no idea how you could come to these kinds of conclusions based on the few seconds of character interaction that we saw.
It's an extrapolation based on the character design of the main character. It's easy to predict what comes with that territory. This shift has been happening for years now anyway, it's just regrettable, doesn't mean it will automatically be bad, it could be a decent story still but certainly more safe and derivative.
"When I was younger, my sole aim was to express myself. If I enjoyed it, and could give the players a product that reflected my own taste, it was enough if it appealed to those players who understood what I was doing. I was compelled by the belief that this was where the appeal lay in an RPG.
[...] When you're young, you're brimming with creative energy after all, and it is a path everyone goes through. Among young game creators today, there is no shortage of people with the same approach I had, making games solely for those players who will understand what you are trying to achieve. I think that this sort of game is necessary in the video game industry.
But now, when I ask myself if I still have that drive, which was in a sense rash and reckless, the answer is of course that I don't. At the same time, I now have a better view of the overall shape of things, and I feel that my creative range has increased. Recently, especially since becoming a father of two, I've been thinking more and more about how to make a game that will be enjoyed by a large number of players and that will strike a chord with them."
