Honestly, probably like 2 posts from putting you on ignore with Ilazy, man. I get that you're disappointed, but half of those are CGI that is in the game at least in some form, or some conceptual video or something like the Dawn trailer stuff that you shouldn't have expected from the game.
From the top:
-The red sky with the thing flying, that's Niffleheim. That's chapter 13. It just doesn't have the red glow.
-The ships flying by and Cor asking if you want to know the truth, the end of chapter 1. Those are very early CGI. I get they make it look more mysterious and whatnot than it ended up being, but that's how trailers work.
-The Adamantoise is totally in the game. It's even bigger.
-The next two looked like they may well be something actually covered in-game. The Luna one could have been interesting backstory. and sucks it wasn't in there. The other one, there's no context there, I don't even know what it was supposed to be to know if we missed anything.
-The big cry was never ever ever ever ever ever ever ever going to actually BE in game. That was an abstract and always was.
I totally get that you were disappointed, but there's plenty to be disappointed in that was ACTUALLY cut without adding every hope and dream you had into the mix.
