The “eSim” REALISTIC Gameplay Mod for PES 2021 by tufkar84 is a tweaked dt18 file.
I am sharing not only the dt18, but also the common folder for those who use the Gameplay Loader.
The MAIN goal of the mod is to basically make the gameplay even more a simulation, getting rid of arcady stuff like PERFECT accuracy or DEEP LINES that make the game easier and funnier for some people, but not people like me. I want the closest possible thing to a football match: very tight, very slow, but with bursts, since we are talking about TOP athletes.
1) having a more compact shape:
Width has been lowered, defensive line has been raised, but not all the time.
2) slowing off the ball players:
I have changed a few values that seem to have an impact on this, but the effect on the gameplay really changes from game to game and from team to team, so not easy to be sure about this.
