This is going to come off as 'non technical', because well, it's my personal opinion of course... Anyway, as someone who's been playing this game since Action: Quake, the gameplay just feels different to me.
The two things I can think of offhand with the limited play I've had so far (about 3 days now) 1) things feel zoomed out (I'm not quite sure how to describe it). I'm sure this has something to do with the vision/perspective of the new engine. 2) the gunplay itself, while having hints of CSGO/counterstrike, feels inherently different. Spray feels different, burst feels different. I'm finding single fire to be way more prevelent then before and headshots feeling different as well.
Again, my personal opinion and feeling of the game. Maybe it'll grow on me with time, but similar to CS: Source, it just doesn't feel the same currently.
To put it into perspective I guess, I felt that CSGO felt more like counterstrike (minus the guys and other technical issues of course) then CSGO did at launch.
So it worked when Trump was elected, but now it doesn't... how are these people on TV?
