Man, Nomura's art was actually legit good when he just stuck to a more "classic" Anime style (like this, and FF7's character designs). His more "realistic" character designs (FF8 and later) are just such complete garbage, what a shame. FF should have stayed heavily stylized.
Same with the environmental art. Look at how drab and bland the environments are in FF15, at least from what we've seen so far (saw a bunch of screenshots in the Console screenshot thread and.... mehhhh). Compared to the amazing, fantastical vistas of FF6 and 7 and even 4 and 5, it's just so... boring. I may hate the game with a passion, but if there's a single thing Xenoblade did right it's the environments and vistas, they really bring about a sense of wonder. Meanwhile FF15 looks somehow more boring than actual real-life vistas I've seen/been to in person, lol.
Having modern tech render the amazing art and fantastical Steampunk world of FFVI would be cool, I'll admit it. But I just don't trust modern Square to get it right whatsoever. Not just the visuals but they'd probably butcher the gameplay and everything else too.
