Hey, you can do as I did, I just play intermediate and play not for win but to enjoy it... and after some hours in the demo, I'm really impressed and enjoying every bit of it! In intermediate difficulty you can really play "real", slow, and see the effects of custom tactics (when the cheats kick too much in World Class, all the good things in the game get lost a bit).
I don't mind playing an inferior difficulty. What I want is to enjoy the game. In Fifa 08 I ended up playin Semi-Professional full manual and enjoying it a lot!
Of course, nothing beats Human vs Human. I've had really brilliant moments in this demo. Yesterday the cpu keeper jumped to punch the ball but collided with Dorgba and a defender and just deflected the ball. The Ballack did a very strong volley and the keeper managed to save BY STRETCHING THE LEG! The ball when to the back of a defender and went for a corner. That's quality.
This game suprasses all the competition of sport games in terms of unpredictability. Honestly, I'm having laughs, emotions and fun playing it, and every day I learn new movements, new things and see new details. It's so deep...
And thanks to Rob, that told me about protecting the ball. It's quality, I got between 2 defenders by protecting the ball and then knogking it off. I have no words for it...
