But any sequel or spin-off of a mainline numbered title is going to need extra efforts by people who have just shipped a big game already. That could be directed towards something new and different, whether an existing IP or a new one. Doing the same shit over and over only gets people (both developers and fans) tired of the same thing.
And make no mistake, if XIII sequels exist is because of how much of an embarrasing mess S-E was during last generation. They might have still made them, sure, but the main motivation was making money back (as a business, a correct decision).
I have hope that they can do something not only better than the last two mainline SP ones, but actually amazing (XIII was serviceable to nice even though I hate it and its trilogy; XV was good but with a myriad of flaws, some of them very crucial): you only need to get Ito to helm it (and create the battle system), your most competent writers (like Jun Akiyama and someone else, but having an gripping story concept beforehand, which XII sadly kinda lacked) and a new artist (like the guy who did the Game Informer FF XV cover, as well as that FFVI-looking Happy New Year card; great art and I'm sure he could create nice designs).
Every FF having a different development team (at least in recent times) and different development times is what gives me hope, honestly. Also, the mistakes learnt from the PS3 era and XV's own faults.
Assuming Square would direct it towards something new and different their shareholders care about sales, why do you think XV is in the state that's it's in, so even if they could doesn't mean they would, not in the slightest.
That's great if you do, but me personally I have no hope regardless of the director, Square was the one that fucked XII, XIII, XIV, and XV unless their management gets 100 percent better, the only thing I can think of them doing with XVI, is trying to make an entirely new engine for it, or something drastically improves from Luminous, but it's unfinished, and they try to ship out the game in 2.5 years of time, when it needs much more than that, and they sell enhanced versions of the cut content, and worse they pull the same shit from FFXV(You can only play as the main character), because they know that will sell, all they have to do is hype it.
I have absolutely no hope for XVI, there is no evidence to suggest that Ito is directing it, no evidence that it will have a good battle system, or even better than XV, no evidence to suggest the story will even be as good, or better than XV. Hell a lot of this hope practically mirrors those that want Versus XV, a director they have faith in, a writer they have faith in, though at the very least they have an idea on how enjoyable it would be considering how some parts of FFXV turned out, at the very least they have assets to work with, so if they decided to pull the whole 2.5 year development cycle they would have some basis that could make it work if it's multi-part, XVI we have nothing no assets they can use, no basis everything is being made from scratch, and considering Square's decisions in the past, it's not the directors that are the problem, hell I wouldn't be surprised if it wasn't the writer that was really the problem, and Nojima's story really couldn't be crammed into 1 game, and the changes were simply made out of writer necessity for example Luna being Noct's bride to be, which is why he's outside of the crown city when it was attacked. Square needs better management that respects their creative talent, and their visions, that don't have unrealistic expectations ie. Trying to get Nomura's version of FFXV out by 2014, on a brand new fucking engine no less, if it was Unreal Engine 4 then I could somewhat understand. Get more creative talent there was absolutely no reason Nojima, and Nomura should have been pulled off FFXV to direct a Remake of a game, when most people just wanted a remaster with better graphics, and better animations, and voice acting, as opposed to the multi-part nature, but if they needed to get this remake done the way it was, it should have been with new creative talent that wouldn't cause XV to lose it's original director, and writer. Until then, they have burned my goodwill, even when I wasn't expect XV to be Versus XIII I was at the very least expecting, great character development, and characters that are used to their full capacity, difficulty that is on par with Kingdom Hearts 2 on Normal, well designed boss fights, they couldn't even manage that. Hell I was expect Luna to be a great character, someone I can definitively say yeah I don't care about Stella anymore, and they dropped the ball hard.
TBH at this point, considering how XV turned out, I don't really care about XVI, I'm at the point where I'm more interested in sequels and spin-offs than anything new coming out of Square especially a mainline title, their management is detrimental to their creativity.
