Fifa 16 ball physics isn't that bad. It's a lil weird passing regard,pes21 do better here, but It is better than Pes one when you shooting and by far.
Body collisions physics is great,while pes21 one is really poor and simplified.
I agree about animation, they can looks odd,but they works fine at the end of the day.
I played both game again in these day,and they really can't be in the same topic if we talk about gameplay.
The perfect game could be fc24 if only EA want It. Cause they are totally able to do that,just they don't want to.
