What? That applies to all GaaS games and anyone with 100 or more hours in a game(per year in this case, 500 probably to play to high-level) will more than adjust to a UI even on a niche platform for what is a console first game, and has been since PS1.
Feel free to upload a video of your old PES and current eFootball depicting the differences that you think make the gameplay a step backwards. Anything I could do in pre-F2P PES I can express less rigidly in eFootball, and the attack/defence dynamic reflects the real game of football even better, now.
A depiction of a Premier league low block is just one example of this. I was playing the other day, and after a minute of camping out on the opposition box, recycling the ball, hitting the woodwork did I then see all 10 opposing out field players drop back along and behind the 18yard box line, and that cross over between real football and PES has never been closer IMO.
If I get a chance I'll capture a match and upload it here to make my point about it just being a lack of experience for most old PES hands, and to show how much more expressive the game has become. but here is an old video I've shared on GAF before of a good goal in old PES.
Last paid PES 2021, master league goal with a poor stats player, but it will show just how rigid/time locked the old animations were and by eFootball standards how little options I had to do anything different in the passage of play and still score.
As for the gambling point. I still haven't bought any currency, or spent any money on eFootball, yeah I haven't be able to acquire players I would like such as: Beckham, Owen, Batistuta, etc that have been briefly offered but developing a all star XI, good enough to win the league or give anyone's AI team a game isn't difficult at all.
