There's a major heap of lack of research and hand waving of history mixed in with decently relatable opinion here, unfortunately. Associating all the "bad things I don't like" with Nomura and the Enix merger is a fine point of focus, but the examples were almost all completely wrong which cuts the point at the knees.

He could have picked more accurate examples, but that would violate his hate-boner for MMOs as a concept that also blinds him to the main hopeful light in the company being YoshiP. Who, in almost every way, IS the anti-Nomura he's looking for. But he'll never see him because his main contribution so far, was an MMO.

I reckon what happened to Final Fantasy as a series is the same thing that happens to all endeavors that grow in expanse. The supporting structure becomes the endeavor once it reaches a certain size, and out of an abundance of caution, the outcome leans as far into safety as possible due to the crushing weight of imminent failure. Being innovative and original is too frightening to consider, and you have to retreat into repeating yourself to guarantee at least some profit.

But even that analysis is very incomplete since every FF game has a huge story behind its development. They have been almost all extremely troubled, wild, and even schizophrenic pursuits individually. All of them had predictable and easily viewed failure conditions they were readily falling into even as an outside observer at the time. The fact that we're on 16 today, despite constant disappointment and failure, really does mean something. It means they're still able to try. That is a tiny bit hopeful, at least to me.
