Hay Chaps so here is my current take on this situation.
I have played pro evo for years and in the follow up to 2012 i was really skeptical after 2011. So i did my homework downloaded the pes 12 and Fifa 12 demos and played them both. Of course the pro evo demo was amazing and felt wow they have banged it on the head this year and another return of pes golden years like with the PS2.
So like many of you i got the game took a few hours to do the GTM option file etc. And wow looks sweet right start a master league with the saints and spend the next year building them up to a world class team. I have always wanted realism i know there not gonna win against prem side etc but i did think i was going to be beat every time. Like most of you i play on top player and have now dropped it down to professional.
On top player the my team AI didn't seem anywhere as reactive to moving forward and creating spaces like in the demo, and as you have all said the CPU has 11 men in defense but there ability to counter attack is not reflected in my teams AI. Also the usual other issues have now come back you can't catch the cpu player if you do they then can dribble though a brick wall it seems and all rebounding and defected balls end up at there feet and player reactions that a human can't physically react in time for. Player assistant (mine was semi) but will never go to the guy you want until the opposition have got possession of the ball.
Now i can see and tell with the new physics and engine that this game has it should whoop 2011 ass (as the demo does) but now it seems they are back tracking and this is worrying.
I am on the 1.02 patch and i don't know if anyone else with this patch has felt this??
There are a few suggestions i have seen the eg superstar mode and just using fully assisted setting with selecting and passing to players. But if anyone else can shed some light on this pls let me know. Shall post my thoughts after changes.
