I still don't agree that FFXV went through a development hell, at least not on the level that we should have ever assumed would automatically result in a total disaster. The game has gone through some big changes (even during Nomura's time with the project), but I don't think any of them are anything too out of the ordinary for big projects like FFXV, in fact there are probably games that are far more different from their original pitches than FFXV that went through less time from announcement to release. FFXV at least partly holds onto a lot of early story concepts (Insomnia's invasion, theft of crystal, a road movie type journey through the world, integration of huge ass summons, ), art style, characters, musical style, gameplay ideas. Sure, most of them have gone through more or less changes, but the core is still extremely similar to what was described early on.I'm surprised all the development hell this thing went through actually delivered a good game. I kinda regret reading the spoilers thread now
At first the game simply wasn't developed by any kind of sizable team for years after its announcement (because it was never supposed to be focused on until after XIII & XIV) and then when they did eventually get around to it after all the fuck-ups with XIII & XIV, it was so late in the previous generation that they decided to move the project to the next generation of consoles. Then they just (or "just") semi-rebooted the game because 1) they wanted to take full advantage of the more powerful hardware so holding on to past work wouldn't have worked & 2) the XIII trilogy disaster had maybe made them realize that they need to move on from the 2006-announced FF games already, so tying the kind of resources to a whole Versus Saga that it would have required for the next decade years before the first game is even out was, I assume, not something they wanted to try again after XIII dragged the franchise through mud. Better to just focus on making one complete game than something that requires 2-3(+) games to fully resolve.
I mean, I guess you can say that's what development hell is (I say it's just delay in full production until they had the resources to focus on it and then a somewhat forced generational switch that pushed them to simplify some aspects of their previous plans), but it's not a similar kind of development hell as something like Duke Nukem Forever that was actively worked on for a long time, and was rebooted, like, 10 times and switched developer studios. The only bigger changes in FFVsXIII/XV are the evolution from the first pre-rendered CGI trailers to what we saw in 2011 & 2013 (which is just natural evolution of any story that goes from early concepts & plans towards a more fleshed out & finished version of the story where some cuts & edits have been made) and then whatever changes they had to make to the story once they decided to shorten the saga into a single game. There's still a hell of a lot that they kept from all the original concepts and tidbits we know of Versus XIII, no matter if there are small & big changes to most of those concepts.
