I've had some really nice matches in this game, but I've also had some of the absolute worst PES-games I've ever had. Sludgy gameplay, some games are so incredibly slow, even though there's no apparent reason for it, the players just move like they have glue under their feet. Some games just ridiculously fast, for no apparent reason, it's not that the game is open and therefore fast, just that the players seem to move a lot faster than what they should.
Also, opponent attackers from crappy teams (like QPR and Norwich) suddenley have attacking players that can dribble your whole team as easy as they like, and score some insane goals (I know Taarabt is capable on his day, but this was with a guy called Mackie or something). The goalkeepers are shit beyond repair, it's embarrassing, I've started a new season with Spurs, and are recording all the goals I score and concede, and some of the ones I've conceded are just ridiculous. Looks like some of the "top goals" scored by people in FIFA, only with shit goalkeepers.
I don't know, the game is so schizofrenic. You can have a string of games that seem so good and realistic (even games you lose, yes), and then suddenley some shit script comes into play and just ruin the whole experience.
I seriously hope someone comes out with a gameplay fix of some sort soon.
