Eh. Yeah probably lol. Like obviously not enough to give away the full story, but, they do take away some of the mystique and surprises. Imagine playing the game and being surprised by Terra/Ven's appearances, by the inclusions of Dwarf Woodlands, Enchanted Dominion, by the opening. Like these are small things, but if one were to go into it completely blind, free of spoilers, I do think it would likely feel a bit more rewarding. Square-Enix's problem with trailers is that, while they only give you little snippets, they give you snippets spanning the whole game, so by the time the game launches you have a general feel for how the story goes -- you know who you'll run into next, to paraphrase the original game's copy. And for me, that does take some of the fun and surprise out of it. It's why I'm going to try to avoid KH3 news as much as possible now, because I want to legitimately be surprised by what the next Disney world I venture out to might be. And I won't if I keep watching trailers lol.
