Agreed. In terms of technical skill, Square is strong as ever.
And they are using Unreal Engine 4, more or less as is, so there's not any weird customizations they've done. The incompetence lie with Square Enix the publisher I believe, not the developers.
That's a producer problem, then, it sounds like.
I don't know the depth of the issues, but I do know that some of the Monolithsoft guys that came out of Square weren't the happiest. Mitsuda, who went freelance, didn't work with Square again for over 15 years. It seemed the big problematic projects were Final Fantasy 7, Xenogears, Chrono Cross, and Final Fantasy 12; and then almost everything else after that. Final Fantasy 7. Final Fantasy 7's 1 year+ delay, which seemed an eternity back then, seems minuscule today.
I describe myself as a little dose of toxic masculinity.
