Indeed it was. Sane, rational fans have no trouble admitting to that from what I've observed. We're mostly interested in how SE handles the story patches from here on out.
Well, since I'm not a game developer, I'm not too familiar with the decision making process of when to release trailers for a game, so I'm not sure why that is.
Again, this goes back to the team originally having confidence and belief that development would've went smoothly, and them showing an early concept trailer was their way of showing said confidence.
I will say this though - creators don't wait for something to be perfect before execution. They just do. They do the adjustments and everything else after the fact, otherwise they'd never get started at all.
If you look at it this way (from a creators point of view), perhaps you can see why they released the trailer, or why the game is what it is today.
I'm fine with creations having imperfections, but as it stands you could practically make two earths out of Final Fantasy XV, the Versus world, and the FFXV we have now hell I think Versus XIII could even fit as a sequel to XV. This is why I appreciate Fallout 4's marketing.
That game was announced 6 months before release, and honestly the game is much better for it, no director strife(Nomura vs Tabata), no drastic jarring changes in vision(shifts from a game with multiple sequels in mind to one game, changes characters around, removes events like the Citadel fight, removes characters, just some significant story changes right before our eyes people), some disappointment yes, but I've never seen disappointment in Fallout 4 to which I've seen for XV, to the point where there are fucking petitions to bring back the Versus project, where rumors are flying about of Versus XV, and people actually wanting that, and tbh Square has no excuse with FFXV, they cancelled Versus fine, but don't turn around and announce FFXV in 2013 when it might not have been ready at the time to ship, they followed the same damn mistake, they announced it too early.
It's not even about confidence at this point it's sheer stupidity. I'm not saying that creators release a trailer the day off the game, no, but at least release a trailer for a game, that has solidity to it again look at Fallout 4 imagine if Square did something like that with Versus XIII, or FFXV, it's not like Bethesda didn't start Fallout 4 and developed it in 6 months, no they were developing the game for years poured there heart and soul into the game, and didn't share anything about it until realistically they knew that they could get it out, Square should have done the same damn thing, this isn't about getting it perfect it's about being realistic.
When can we get it out 2016, ok then let's show it in 2015, let's learn our lesson from Versus XIII and not get overconfident in the game releasing in 2014, and show it off when it's near ready for release, have plan, just like Bethesda.
If they just had simply done that, there wouldn't be no Final Fantasy Versus XV reboot petition, there would be no Final Fantasy Versus XV reboot rumors, there would be no Nomura flogging, or Tabata flogging, there would be no Final Fantasy XV fans, vs. Final Fantasy Versus XIII fans, Nomura can't finish games wouldn't be a thing, Tabata ruined Nomura's vision wouldn't be a thing, there would be no Stella vs Luna, there would be no Versus XIII Noctis vs XV Noctis, if FFXV even then, if they did what I think they should do from now on, still released the way it did now, there would be some disappointment, but not to the extent that you have a entire group of people that look at old trailers and feel dissatisfied with the final product, you won't have people wishing it was like the 2011 trailer in terms of combat, character switching, and magic system, you wouldn't have anyone wishing FFXV was just it's own game unrelated to Versus XIII, and the FNC, there would be no petitions to get Nomura back to direct, there would be no Versis XV rumors, and even if there were only 10 people might care, because we wouldn't have ever been shown Versus XIII, it would've just been Final Fantasy XV, people would've played that and much easier would be willing to move on to XVI.
