Ok someone else...I posted the same thing on PesFan earlier today. I completely agree with this - the full game does not feel right.
I've been playing it pretty much non-stop since Thursday morning (40+ games) and I can't get in to it; it feels a lot more rigid than the demo, fouls seem far more inconsistent, player switching is worse & the collision system seems a bit of a mess. I get crosses go in to the box and I seem to have no control over the players waiting in the middle, in the midfield the ball bounces around like PES 2010...the only positive thing is I feel the shooting is a bit tighter & obviously the choice of game modes are excellent.
I played the demo for 3 weeks solid and absolutely loved it - I was so excited about the full release but I now feel really disappointed. I decided to give the demo another go this morning just to check I wasn't going mad, with Barca v Bayern, then went back and played exactly the same fixture on the full version and I'm now positive I'm right...the demo feels so much smoother, I honestly don't know what's happened to the code since, it's such a shame.
I'm going to keep playing and hope it clicks but at the moment I'm really confused - hardly anyone else has mentioned this across all the regular PES forums, so maybe it is just me (and a few others)!
