Just played my first match, Bayern vs United. Looks great for a demo, plays quite well as far as passing game and movement, excellent animations, can actually employ different styles of football and see them playing out. Players feel quite unique when under player control and it's a nice challenge adapting to what they bring and making them all work together. I'm going to fiddle with the game speed and learn some of the new controls tomorrow. Shooting seems a bit different, I played on Superstar difficulty and drew 0-0, had 75% possession and created some chances but couldn't get anything on target, placement seems even more sensitive than normal for PES. Pace also seems to be implemented differently than previous versions, but I can't quite describe how yet.
Immediate thing that stuck out as a negative is the AI's seeming obsession with dribbling, I guess so the developers could show off the "independent ball". Every single AI player will dribble basically until he gets clattered or otherwise dispossessed, doing little turns and feints no matter who it is. That really loses any "cool" factor after Michael Carrick has dribbled out of his own box all the way to yours doing 14 fake passes and sidesteps along the way. This will be hell against the Barca/Madrid abusers online. Strength Stat-based strong-arming opposition off the ball looks to have made a comeback, which should be great for any of us playing as Villa, but perhaps a bit too effective (though similarly strong players can hold each other off and properly battle, which is nice). Assisted player switching seems touchy, but that's a problem in every sports game ever, imo. Will eventually go unassisted, I'm sure, though response to click seems a little slow and the player you want to switch to will often perform AI-queued actions (in response to your last action) before you take over, a couple of which seem potentially exploitable. There are, however, a crapload of AI Assisted settings that I haven't found/disabled yet.
