These photorealistic particles and lighting really kill the visuals.
But the only way companies can manage to greenlight these types of projects is by cutting corners somewhere.
Unfortunately its the characters that pay the price.
Modeling all of the characters and enemies in 3D, texturing and rigging them all is a lot of work.
Since this is a niche product, there's really not much they can do about it. They're not gonna get a big budget to work on remakes.
On the other hand, they could have attempted something like Bravely Default or FF3 DS instead.
The scope is more realistic, and things become more manageable.
But I suppose you can't wow your superiors or investors that way.
Such a shame.
