Got the demo yesterday and I have to say, like last year, the impressions are good.
Passing and player movement is much more fluid this time, and not sluggish or blocky like in PES 15. I can definitely see more improvement in this field since last year compared to FIFA.
However, as much as I would love to get PES 16, which may be likely since it comes out first, I will probably still end up getting FIFA 16 as well simply because most of my mates play it and that is also a huge factor why I also ended up getting FIFA 15 after PES 15.
I agree about the graphics. They look great and vibrant, but also quite cartoony in comparison to FIFA which looks more realistic.
So I think I might just end up getting PES on the XB1 first, and then FIFA on the PS4! PES for the gameplay (plus scoring is more satisfying), and FIFA for the multiplayer.
