Well after playing the demo over the weekend I'm in the middle. It does some thing right and some things just irk me. Graphics are pretty nice, especial during the close ups, and the basic look and feel of a game of football are in place.
But a lot of the stuff that makes me frustrated with PES are still in place. First, the back line defense for both you and the AI are just a mess. They don't mark runs correctly, they don't step up to promote offside calls, they get beat by long through balls all game long, they jog to catch up to an attacker that beat them...
Your goal keeper is just bad at his job, If the AI gets a good shot on goal, it is almost a sure thing. But the AI keeper seems to always be in top form. Most goals against the AI seem to come from breakaways, rebounds, or deflections.
Then there is the tackling. I have no idea why if the AI performs a standing tackle on you the ball always seem to either go right to one of their teammates, or it goes a few feet away from the player you are controlling but you are unable to chase the ball down because the game delays your movement for a second or two, allowing the AI player to gain possession of the ball.
The balls played in the air nee a lot of work. It's just two players stand completely still, lock next to each other waiting for the ball to get to them. There seems to be no fighting for position.
And finally, your shots on goal seem to always be just inches wide of the post, or routine saves for the keeper. Unless its a volley shot, then those go just inches over the top of the goal.
I'm not a huge fan of this years FIFA demo either, but if I had to pick the game I more enjoy playing, it would have to be FIFA right now.
