Probably will get shouted down for this, but my two cents...
Not hugely impressed with it so far. I'm very much a casual gamer these days (and exclusively single player), but I'm pretty much experiencing the same issues I had with the last few versions of PES so I think I'll give this a miss (unless, of course, Konami be Konami and release a full game that bears absolutely no resemblance to the demo...).
I got bored with the last one after about a month, largely down to the awful AI, scripting and general repetitive nature of matches, and I'm still getting a sense of that with this even despite playing only 25 odd matches so far. Just a few of the issues off the top of my head:
- AI seems horribly robotic and predictable. It's hard to put into words, but you can almost tell when the computer is going to score, or intercept a pass, or control a hopeful 70 yard punt up field instantly, or time an inch-perfect tackle when your striker is through on goal - there doesn't seem to be any degree of variety or randomness in the play.
- Attacking headers still seem floaty and unrealistic. In fact I can't really remember scoring a bullet header in the last few versions of PES at all. My biggest gripe is when two players go up for a header and it comes off one head and pops up about three foot above them both to challenge again - honestly, how often do you see that in an actual match?
- Through balls and attacking movement continues to be frustrating. Why run beyond the full back into the massive chasm of space when you can just stand there hugging the defender, thus not giving me an option to pass to? Argh.
- Responsive times I've found to be slow, particularly when switching players and in crucial moments when it's most necessary, for instance goalmouth scrambles.
- Goalkeeper animations are still poor. They're good for shot stopping when it involves palming it away, but the catchng animations (especially that horrible floaty two handed catch animation) largely look really dated and amateurish.
- Rubbish menus with graphics that look about 15 years old, no sense of atmosphere etc, but I've really come to expect that with Konami over the years, so that lessens the blow somewhat.
- All in all, add up the above items and it leads to very few 'wow' moments, if any.
It's not all doom and gloom mind, there are some things that I think have been done well. Match graphics seem to have been improved and player models are excellent (Konami has always done this a thousand times better than EA Sports in my opinion). Players seem a bit weightier and better to control, and I'm quite enjoying the tackling system, especially after the shambles that was the fouling system last year. Although the five minute halves means I'm massively rushing around and conceding loads of fouls mind.
Given the feedback in here so far, I think I'm probably out on my own with these issues. Not hugely enamored with it so far.
