I had some quite enjoyable matches last night, still playing exhibitions while refining some sliders. I was encouraged by the variation in the games, which feels better than in previous versions.
I tried some of the 'Live Matches', including QPR v West Ham while it happened to be actually live. There was an odd coincidence when in-game Kevin Nolan was booked

less than thirty seconds after I'd just seen him being booked on the television
A nice moment was when I cleared a set-piece high into the air, and as the ball dropped it was Bobby Zamora and Mark Noble competing together. With the size & strength advantage, I simply held RT (shield) while the ball was in the air and Zamora just leaned his body back into Noble, holding him off and preventing his smaller opponent from managing to head the ball, able instead to bring it down. Whereas if I'd tried that against James Collins he probably would have gone over/through me and headed it.
I then played as Barcelona away at Sevilla, losing 2-0 including a top-corner screamer by Trochowski. I was able to have a Barca-esque 60%+ possession, but the closest I came to scoring was when Jordi Alba overlapped and hit the post. Messi frequently dropped deep into midfield like he does, and Busquets was a constantly available 'release valve' for Xavi & Fabregas if they were pressed, as he is IRL.
Then I went to the other extreme and played as Rotherham against Oxford in League Two. This felt very different, two much more rigid teams of lower quality, players further apart from each other. Possession was 49%-51% in an enjoyably scrappy game of bad touches and physical battles, finishing 0-0. After the short fluid passes of Barcelona, I was now instead trying to fire the ball long to Odejayi and use his strength.
Finally, I tried something different with a Be A Pro game as Hernanes for Lazio v Udinese, in Rome under the floodlights. I think PLF is right, your AI teammates make BAP quite enjoyable nowadays. I earned a penalty when a swivel of the hips attracted a defender's lunge in the area, and Klose converted... although Udinese would level later on.
I definitely think the game benefits from a reduced Acceleration slider, feels like it 'weights' the players down a bit, and raising the First Touch Error slider is fun too. The speed on Slow with edited sliders has not been a problem for me.
I also experimented with disabling the commentary to see what the crowd audio is like without it, and I think it is definitely improved this year (although I also have much better headphones for my PC compared to what I used before on the 360, so it's not the fairest comparison). I'm currently trying to download
commentary in other languages which, if it works, could add to the variation too.
My only real negatives at the moment are, as ever, the already much-commented passiveness of the AI defenders not nearest the ball, and also bemoaning the return of the magnetic ball after I'd been convinced it was gone from the demo. And there's also an odd bugged behaviour the AI very occasionally adopts when they start playing strange one-touch passes in their own area. Otherwise... fun had.
