Then looking at stuff like this
vs
I feel like the look and feel of versus was more unified and coherent than the one of FFXV. Like I said, it could have a lot to do with graphical quality, but aside from that, versus's colors seemed to have more "pop" or saturation which I feel helped the realistic and unrealistic aspects blend in a more even way.
No you are definitely right, I've felt this way for a while. Versus was very dingey, yellow, and had this unifying grit texture like in the E3 2013 re-reveal trailer, and all those early examples you've shown. Everything so far in ff15 seems a little less textured and smooth, kind of lacking that gritty texture. Could be because of the director change, could be because of a different art director, could be because of a different team all together. Could also be because they are going for a different mood here. It's basically someones job to make sure it's unified, and I definitely think they can push that a little more in some places.
What's interesting is those versus shots, everything looks abandoned like it's been devoid of humans for a while, which is pretty cool, so maybe this is a different area in game, seems to be like a desert sand area. Duscae is putting off that vibe that humans have been inhabiting that area for a while, hence why the gas station is more lively, and it's more lush with grass and forests, I doubt the entire games landscape will be like that though.
Also I still really like the versus gas station.
