I've been playing WE2015 (PS3) non-stop for a couple of days now. Haven't slept much. This game is simply incredible. Exactly the kind of game I have been waiting for.
I play in professional difficulty and one bar passing and semi assisted cursor. I have NOT played as or against these teams - Real Madrid, Bayern Munich, Barcelona, PSG, Man Utd, Juventus etc. I've been playing as Chelsea (my team), Everton, West Ham, Newcastle, West Brom, Valencia, Villareal, Roma, Napoli, Boca, River, Schalke, Southampton, Marseille, Norwich, Japan, Colombia, Chile etc.
The game is incredibly addictive. I just can't let go. Every team plays differently. You'll realise this only when you play a varied set of teams as I have. The game is not skewed in favour or against any particular football style. So it's upto you what you play but you make your choices based on the players you have.
Yes, the fatigue catches up but not as bad it's made out to be. Beyond 70th min, the acceleration takes a hit and hence the bursts become harder. But I have created and scored with players who are running on zero energy too. Subs when made right make a big difference. That's how it should be.
I have lost most of the games but honestly I can't say I have seen any instances of scripting in AI's goals or wins. Will play, review and report more later.
