I've been trying to go up from Regular to Professional on PES2021 recently, just for context I'm playing FUMA. All of my mixed feelings towards how this one installment played have taken a turn for the worst with the difficulty increase, as it tends to happen with FOX Engine PES in general... I'm still enjoying it, and over the years I've been trying my best to be less of a sore loser and just enjoy my experiences, my football in this case, but honestly... it's just disappointing, I looked for an used copy at a decent price for quite some time, and was so excited when it arrived, the last PES, full of support from the editing community...
I mean, it should've been perfect, and it started out well enough, I saw praise for PES2021 among most people I know that play football video games, and on things like YouTube and stuff, but now I'm starting to think people go a bit easy on it due to it being the last PES before eFootball ruined everything and/or all people think about is the PC version which has ton of mods to essentially turn it into a completely different video game... I've had some decent matches after switching to Professional, but haven't won any of them, and can barely score, also have been conceding the exact same goal, over and over again, non stop.
As the difficulty goes up, the CPU wants to score more than before, they become more direct and accurate, and how do they go about this? Well, the defense AI doesn't seem to make any effort to block passing lanes, so they usually get close to the box in a few passes, and at that point there's a risk of a foul being given even if I tackle them pretty much perfectly, as the referee is very poorly programmed overall, often having nonsensical criteria for fouls, and ending one half or the whole match during a dangerous counter, anyways a free kick near the box for the CPU is a goal, it makes defending a chore, 50% of football... Overall, compared to PES2018, the latest one I owned before this, FUMA feels more off, with the player switching being way worse here... also, the shielding mechanic is somewhat exaggerated, not only that, but physicality has become more relevant, and as the difficulty settings increase that only gets worse... it's barely possible to beat the CPU defense on a run when you're on Professional even with a head start, they catch up and start getting physical, and it's never a foul, but my good tackles on the ball? Oh, those are fouls, and often end up in goals. I'll insist on Professional a bit more, get better at it, but this isn't fun...
PES2021 really is just another FOX Engine PES, a solid core, lots of good stuff, full of potential... and none of it is ever fulfilled, so we wait for next year, but now we don't even have that anymore, no hope of improvement, this was the last PES, and it was solid, but mediocre package overall. I'm disappointed in it.
