I can't recommend FIFA 16 highly enough.
I'm almost stunned at how good the AI is.
I have a set of sliders that is making the game run fantastic. The pace is actually decent (much slower than other FIFA's), and the AI is just great. The ball is actually loose, and rather unpredictable. In all the past FIFA's, you pretty much always kind of felt that one person "had possession" of the ball, even if it was in the open. But this year, it seems like when someone takes a bad touch, it doesn't just automatically go to a place where the attacker will be able to get it again. But this year, there are plenty of times when it feels like it's a true random bounce, feels so organic.
For the first time ever, the midfield actually means something. I was REALLY struggling for the first 10-15 games or so that I played, because I was just doing the same old ping ponging up the field that I've kind of been programmed to do against the FIFA AI, but it doesn't work this year. It forces you to play a possession game, with smart passes in the midfield.
If you are patient, the AI will open up, and you'll create opportunities, but just banging it up the field and going over the midfield will more often than not result in the AI easily getting the ball back.
It's a wonderful game. Bravo, EA.
