I've chilled down to "maybe it could be acceptable in spite of itself" on this. It actually does have main staff on it and it's sounding like the underlying gameplay is actually likely right, whereas rumors pegged it as westernized and dumbed down, so that at least quells some of what would've pissed me off most.
All that said, if it succeeds for me at all, it'll be in spite of everything they've shown, not because of it.
Like, maybe stealth will be easy to ignore, impossibly dumb as it is. Tracking... tracking actually worries me above all else as that sounds harder to avoid and could slow crap down a lot.
Open/seamless world is eeeeeeh. I see zero real advantage to it (I guess no minor loading? But it's all about fighting monsters in arenas, so being in zones has never been something I wanted to see go away), but maybe it won't be that negative of an impact.
Destructible environment to effect the battle I'm meh on, sounds very take it or leave it to me. Monsters fighting each other I actively don't like, sounds freaking bad as an actual gameplay thing. Like, all that can do is make things waaaaaaay easier.
And then the new monster looks HORRIBLE to me, like possibly the least I have liked ANY large monster in the franchise, so it's worrying to me that they're leading with it.
Sure, fancy new graphics are nice I suppose (though honestly I was fine with janky old 3DS graphics, and much as it was gonna happen eventually... there's like zero percent chance this content matches the 3DS games in terms of monster count at all, and that's gonna hurt.), but I'm not liking all the stuff that comes along with it.
So I dunno, I'm still grumpy, but I'm less raging grumpy at least, and willing to wait to see more to hopefully at least mitigate some of what's rubbing me so wrong.
