I thought i would leave my review until a week after playing the demo to put my true opinion of the game in my review rather than something hasty. Fifa 11 definately is harder to play than Fifa 10, but i remember saying that when playing the Fifa 10 demo when Fifa 09 was finishing. The player personality definately makes a huge difference now, as each player can perform certain moves/passes/shots in different ways. All of the old easy goals from Fifa 10 seem to be non-existant and some of the silly long throw ins off the bar and RB + Shoot always in from long range have gone etc.
The passing seems to be alot better now, you have to be accurate with passes and balance comes into this alot, like it does in real life. Shooting seemed hard to start with but you just need to keep at it. The main thing is to not think you are playing Fifa 10 and nearly start your game play from scratch.
I also think when you do manage to score a goal on expierienced level it is very rewarding as there arnt many opportunities to score easy goals any more. "We say that but within a week of playing the real Fifa 11, we will know the easy goals"
Overall i believe with the new manager mode, new in play upgrades etc will be best ever Fifa and will blow PES out of the water!
