Don't be angry with me,

I'm sorry, but... I'm not one of those who can agree with your statement... because it's a technical wrong affermation from outset by my point of view...
My focus it's only the question of graphic "game" engine used (and I can understand who played only on consoles with vanilla pes2021 gameplay)
Gameplay's behaviour variations don't depend on the PS2 era game and their graphic engine but only by the gameplay parameters used ... even PES2021 can have completely different situations if you apply different game mods on PC (it's not true that they're all the same and nothing changes)...
Meanwhile, the eFootball graphic engine is rubbish because it has been choosen (castrating the last pes2021 game) literally in order to adapt it to mobile phones and online gaming and to facilitate cross-platform play later on, precisely for online gaming with a free engine without investments by konami
Sincerely every time I play pes 2021 (on PC with gameplays mods and not with vanilla gameplay that was not good) It is no longer possible for me to go back to playing PS2-era games and their 8-direction graphics engines. I open them every now and then just out of pure nostalgia, but boredom overwhelms me almost immediately, and even though I was a big fan of them at the time, now looking back and saying that I enjoy them more than I do now with the gameplay mods on PES 2021 would be something I would find completely untrue... but the world is beautiful because it is diverse...
Let's be clear, I've been playing since the PS1 era, when I already loved the first Winning Eleven games, and I've played all the Konami games as well as being a modder since 2003 on PC, But my tastes have evolved along with the game over time, and I've never looked back...
Often, I had to relearn how to play with each new game of new generation, and the learning curve became more difficult, but I can never say that I prefer the old graphics engines to the latest Fox Engine of PES 2021 just because there was gameplay variability at the time, because, I repeat, it does not depend at all on outdated engines with players running on 8-direction tracks but only by parameters by konami developer in their gameplays
When I finally (in 2025) managed to get a PC that allowed me to play PES 2021 (before that I only had an old laptop where I had stopped at PES 2017), and I saw the gameplay of PES 2021, it motivated me to devote myself to modding the gameplay itself.... Vanilla one was disgusting for me... while in my opinion, the graphics engine is still the best engine available for current football games on the market.
So, I can only understand why someone who doesn't have a PC with PES 2021 modded might still prefer certain old games, because the vanilla gameplay is actually sickening for sure...but it's not the graphic engine the point
