The game gets quite annoying when it comes to shooting, passing and dribbling, which is all extremely hard to control.
PES 2012 took everything good from those old versions of PES, and then it took a major load onto it. And a result is this crappy game, which is so much annoying and not fun at all.
Difficulty level would be ok if you could control your players like AI controls it. Shooting is very very very hard.
You can dominate the game entirely, but you can loose at the end because of the stupid things like shoot, uncontrollable passes and enemies dribbles that are impossible to stop.
You will find yourself 1 on 1 with the goalkeeper for so many times, and you will score only 30 percent of the time. And the point of it all is, that you don't quite get why the hell did you score or miss. Some players like Cristiano Ronaldo, Messi and other great shooters have an amazing shot, but even them score hard.
Those things simply destroyed PES 2012 which is almost unplayable. If I wasn't such a PES fanboy, I would give it even a lower mark, but this 6 is quite bad as it is.
