What I really love about PoE is the color scheme. Somewhat darkish, but not dull, with some intense lighting where it is necessary.
In fact, I can not force myself to play some of the recent games because they look like an exploding circus - bright, unmatched, unnatural colors, extremely colorful animations for routine actions etc. I mean, I understand it is done to attract kids and teens (it is a well-known psychological phenomenon), but it doesn't make it any better.
I expect the 3D models to be polished by the time the game is released. In fact, the moment I noticed PoE would be Unity-based, I was like 'oh crap, not that!' cause I have seen (and funded) some not-so-great examples of Unity-based games (MechWarrior Tactics and Shadowrun Returns - first being unoptimised and eyegouging, second feeling empty and incomplete). But after I've seen some gameplay footage, I am quite sure PoE will be great.
