My biggest takeaway (other than the Domino's Double Decadence pizza I had last week) is that, it's different from PES 2020/2021, and therefore I'm just glad we will have something different to play this year.
It does feel, as
@Emroth says, like the mobile version ported to PS4/PS5 (I'm on PS5). Nothing more, nothing less.
Which suggests that their base for their super-amazing next-gen wonder-game... is a mobile game. Yay...
It's clearly very early though. There's no individuality whatsoever, every player is the same (but I don't mean that in an exaggerated way, I mean literally, I don't think it's been coded in yet that attributes make a difference).
There are also zero offsides (in the games I played anyway) - the AI is just positionally perfect, so they never happen. It seems to me that "error" or deviation just hasn't been coded in yet.
Now, either that's to make the game quicker (for mobile players) - or this is new code that's at a very basic stage. Does anyone know if the mobile version has these two issues (no real individuality and no offsides)?
I also didn't see a single foul (without deliberately hacking down a player with the slide tackle, at least), but I've read others say there are too many, so I'm not sure what happened in my games...!
There ARE positives though. While everything is still very much "one speed only" (you don't have stages of play that are much faster than others, or rocket shots - the players and the ball move at the same speed all of the time)...
...I DID see more variety in shots, with long shots having MUCH more of a chance of going in, and dribbling felt a little more fun to me, with less "stickiness" and/or lag when it comes to controller input.
The reason being, the ball seems to actually be a separate entity now (HALLELUJAH!) - or at least, it has much more freedom. I didn't see goalkeeper animations speeding up so that they always save certain shots, either.
All very interesting...
