That's interesting, but in what way, do you mean? Does the game feel different when playing 15 minute games, or is it just that the games are longer which will give a match more depth? I'm intrigued by this.
Also, what difficulty and game speed are you playing on? Any other settings you're using worthy of a mention?
I too find manual passing to be almost too manual. Been trying hard to get into it, but finding it nearly impossible to keep the flow of a match going if I'm on full manual. If I'm using the L2 manual, it feels a lot more natural somehow, maybe it's just because I can see the arrow, but it somehow feels a lot better and precise to me.
Also, is anyone else feeling that just holding X and square while defending and pressing the opposition is a bit too effective? Even on Superstar I tend to be able to get the ball from the opposition just by pressuring them sky-high with holding X and square.
