........ Is there anything in pes2020 thats better than pes2021? I don't think so..
Much better tempo, under human control at least. It is easier in PES 2020 to maintain a 1-0 match in Master League.
In 2021 due to better responsiveness (with great power comes, great responsibility though) , comes as side effect that a lot games against CPU go frenetic end-to-end . Plus you are forced to hammer CPU with consecutive attacks, or else it is more difficult to maintain a gameplay tempo. I have a lot 3-2, 4-3 matches.
In 2020 when i lead 1-0, i know that if i have better players, i can chill out playing tiki-taka in my 2nd third of the field. In 2021 no matter my team OPR, it is impossible to play relaxed near the midfield, i am forced to attack and get counter attacked , more end-to-end.
Basically i concluded that all the above come form enhanced responsiveness. It is like cherry-picking, either better response in 2021 with its sideffects good & bad, or mud-effect movement in 2020 with its sideffects.
Final judgement. I cannot disagree that 2021 is an improved 2020, but both games look like they were designed for 10 minutes box-to-box, end-to-end crazy action highlights gameshow. Midfield is still nonexistent when ball gets hot.
P.S.: I have not played PES 2021 before datapack 3.0, but in 4.0 and 5.0 collision detection seems at its worse, it is either very random or the referee is biased, sometimes towards the players, other times against the player. I can't explain better some crazy ref decisions i observe in every match here and there..
