Played this for about 6 hours yesterday. Combat feels good, kind of like Assassin's Creed if Ass Creed's combat wasn't shit. You also have eagle vision / Batman's detective vision, so you spend a lot of time looking around for clues. I've never played a Witcher game before but you don't really need to for this one, which makes sense, that "III" in the logo for less prominent as development went on.
The world is beautiful, it looks especially stunning on PS4. I can't recall a game where the trees move in the wind, the visuals work great with the top notch sound design, so when the wind's really blowing, the trees really move and you hear the wind howling too.
I have yet to try it on Remote Play but a giant huge RPG like this is exactly the type of game you want RP for.
Anyways: game of the year.
