I'm referring to the fact that they have a very real development culture problem at Square Enix, and Nomura is part of that problem too. It takes tens of millions to develop a game. They have limited resource. Their development leaders need to operate with this in mind, and at times, they don't seem to. Square Enix made Final Fantasy XIII, and in the process hurt their brand with multiple sequels. Not because they wanted to, but because they pretty much had no choice at that stage due to the investment made. There were plenty of other problems that I don't feel need to be reiterated since everyone knows.
Nomura was creating Versus XIII through a trial and error method. He was pretty much testing what could be done, and what couldn't. As he did this, things kept getting bigger, and more ambitious, and the timing became problematic. Now, he did kind of have time to do this initially since the company was occupied elsewhere, but once they suggested to him to change the project to Final Fantasy XV, and he agreed to do this by the way, then it was time to focus. Moreso when it was decided it would be a current generation project. You can't be overly ambitious and plan things that may take so long to complete that it interferes with the company's plans. Development takes a long time.
Around that period, Hashimoto wanted to get FF7 Remake done. This was in 2013. They also have to factor in what they're going to do beyond XV. How can Square Enix devote that time and money to a project that could take a decade, if not more, to complete the way Nomura envisioned? What happens to XVI in that scenario? Since it's very unlikely the entire XV project would finish before that game is done? What happens if you run into problems with the subsequent XV development, or things get delayed on that end?
You have a real problem there from a business point of view. That's not even taking into account the fact that XV releases, doesn't light the world on fire, and the sequels/expansions have diminishing returns that aren't worth it. They experienced that problem with FFXIII. This part is very much Nomura's fault. He didn't have a clear direction for the game, and kept letting things get bigger and bigger, instead of reigning things in, and getting them done. It's also SE's fault for allowing things to get to that stage rather than getting things in order. Fortunately, as is apparent, they didn't wait too long to fix things this time.
Their leadership made the smart move, and put him on FF7 Remake, while FFXV is getting finished, and FFXVI is able to progress. That's three big games, rather then spending an entire generation with FFXV and it's "World of the Versus Epic" or whatever it was supposed to be.
