I have played FIFA for about 20 years and I remember every years improvements in fifa games. One thing that I like about easports is that they don't step back in making games. It may be a very little improvement but always there were improvements in their games.
About Fifa 22, Honestly the graphics doesn't change from 21 or even 20, it maybe because of the switching between ps4 to ps5. But player physics, ball physics, player AI, and many other things are better than before. The ball moves more real, goalkeeepers reactions are much better than before.
