Giant battles are tricky as fuck, only a few developers have managed to actually make them fun and original (the king is still Shadow of the Colossus). More than the bombastic nature of it, I think that the GoW get old fast because of the repetitiveness of the enemy's attacks and the limitations to your own movement.
Given how big some enemies are (the Behemoth is not even that big compared to others we've already seen) and how focused Noctis' combat style is in regards to air combat, I hope it is fun and engaging and not frustrating: the ingredients are there.
Also, totally unrelated to any ongoing discussion, but man, do I want to see alternative outfits already (and know whether we can play without the jacket or not!). I'm guessing they're announcing them rather late in the marketing plan: hopefully, a chunk of them are free and there's variety in number and style. And if only we could shorten Noctis' back haircut a little bit, I'd be the happiest.
I know I've said this a loooot, but I'd love for Noctis' placeholder cloak to be there, just for the sake of nostalgia. But, again, I don't know how their contract with Roen is. I kinda wish it didn't exist tbh, as I preferred the old main costumes (current Noctis would be great with a shorter jacket and longer trousers; the rest, except for maybe Ignis who is largely the same, were better before). The formal suits are stellar, though and so are the other outfits shown, whether modern or fantasy-oriented.
I find the design changes of this game to be fascinating; hopefully the Ultimania has some insight in the Versus days (whether pre or post-Roen), although I doubt it's going to be much and it's mostly going to focus on the Tabata era.
