FF16 is even less of a FF game. Some DMC fans seem to have liked it, though, but not enough to fill the gap while waiting for another DMC. Newer and older FF fans seem to have hated it, and the only people who thoroughly enjoyed it were either new fans of the series or people who don't mind the genre shift. At least you don't win by just pressing a button like in FF13 and 15.
I haven't played it, but the biggest sin this game apparently committed is not having a clear goal of what it wants to be. Everything, except the music, is all over the place, and not in a good FF way. That's the summary of what I've been hearing.
I think what hurts the most is that, at the end of the day, it's still the same old heads who made the older games at Square Enix, including veterans from the Squaresoft era, so there's no way to scapegoat this as a bundle of decisions made by modern times or dumb devs with no experience. I think this franchise is cooked if Resonance doesn't do well.
