Essentially, the game looks like PES 2014 running at 60fps and 1080p, but the gameplay is improved.
Juve v Bayern.
Gameplay is much improved over 2014, faster and less clunky.
Graphically the same, but 1080p, 60fps. Faces and facial expressions are better. Crowd is better, but nothing that stands out.
Animations are pretty much the same, noticed that there's more physicality to jostling.
Still plenty of time to go, but the main improvements are the ones mentioned.
Left a bit happy because fluidity is much better than 2014.
