Okay, played a few games on demo 2, and I love it. The differences between this and the demo are subtle, to me barely noticeable, and I think it's the best PES I've played yet.
Tiny issues in demo 1 that popped up from time to time, like player switching, haven't been an issue (that's not to say they've been fixed, I just haven't had any problems with it yet).
Shooting is perhaps toned down by a tiny percent, but you can still drill shots pretty hard if you know what you're doing. I don't see why there's so much moaning about this.
Passing, well, I don't notice any difference at all. It is 'soft', but you can charge up the bar more to get a really fast, zipped pass along the turf. I think people simply need to adjust to using the full range of the power bar a bit more, it takes more power on shots and passes this year which to me is great as it opens up a greater variety of things you can do with the ball power.
Other little things really stand out though. Controlling Barcelona really feels different to say, Junventus on the demo. You can perform really intricate passing in tiny spaces with Barcelona. Try it with other teams and it somehow doesn't quite come off in the same way.
The only thing I don't like are that long passes, where you could hit quite snappy long, dipping crossfield balls, have been toned down and while the trajectory of those passes remains the same, they are a lot more 'floaty' than before.
There are some changes in the audio. The ball sound when kicked is greatly toned down, you no longer hear a giant 'thump' when you kick the ball, which is vastly more realistic. I think it has an almost counter productive effect in that the toned down kicking sounds trick you into thinking the ball is being more 'floaty' than it actually is.
The other thing I really enjoyed was the crowd sounds when I played between Barcelona and Valencia. Konami have made a real effort to make the crowds sound authentically Spanish, especially when a goal goes in or a chance goes wide. Combine this with the La Liga stadium DLC and Master League looks good this year if you're gonna choose to play in Spain.
Back to the game, I've found dribbling to be more difficult, which I expected as I think they toned down tackling in demo 1 to allow you to experiment a bit more with player ID, but I've still managed to score a solo goal with Messi that had me out of my seat. Player ID is still very noticeable.
I was quite pleased with possession stats too. Most of my games I've had more possession, but at around 54-55% most of the time rather than the incredibly high 70% in demo 1, so I'm pleased with that too.
I just don't get some people's moans about the game. It's not pedestrian at all, just use the power bar more if you want to quicken the pace of the game/passing. It has a range, use it.
Graphically, the game is a slight improvement on 2012, so anyone moaning about the graphics need a reality check. We all knew months and months ago that the game would be virtually the same visually, so complaining about the graphics now seems bizarre.
All in all I love it, it's still a giant leap over 2012.
