Considering this is only the demo version, I am very impressed. EVERYTHING has improved, as far as I am aware. I just hope they don't mess things up once the full version is released.
The gameplay is very realistic:
it is very fluent & smooth
the A.I. is ALOT smarter, for both Player and CPU teams, ie. players make more runs, get into better positions, improved man-marking.
The menu is quite similar to PES 2011, quite complicated in my eyes. I wasn't a huge fan of this menu, I'm more of a fan of the old skool menu where it was basic and user friendly. Although I'm not too fussed because its the gameplay that counts!
FOULS - as most people know, the fouling system is RUBBISH! All it takes is a slight *nudge* and the ref blows the whistle for a foul....... NOT ANYMORE!! On average, there are 3-4 fouls per match (10mins). The players are well balanced and stay on their feet, they definitely don't go down as easily. This is a huge improvement, I don't hear the whistle even half as much as I do in PES 2011.
I've found it is alot harder to score (Top Player difficulty). But these are early days, I've not had much time to practice.
The AI is VERY unpredictable - its extremely difficult to read their next move! Its harder to tackle the AI - it seems to be able to read your moves, it has a mind of its own and has more variety - rather than a robot-looking figure heading in the same direction.
I've not found a single flaw in Gameplay, so far. Which is HUGE, as I normally find something straight away. I hope it stays this way cos I love the Pro Evo series, but these days its on par with FIFA.
I'm trying not to like this demo too much cos I wanna give the Fifa demo a fair trial too before I choose either one, but I can already see myself buying PES 2012 at this rate.
If FIFA wants to stay on par with PES this year, it MUST have alotta improvement. Its gonna be a tough call...
EDIT: After playing the demo ALOT I found a major flaw - passing! It will only accept your first decision with the direction of your pass, eg. If you press PASS to the left direction, but you suddenly decide to pass the ball to your right at the last moment, it will NOT allow u to pass to your right! It will only accept your first decision. This flaw may be fixed on the full version, but it made such an impact on me, I have switched to FIFA for the first time, ever!!
If anyone else happens to notice this flaw on the full version, please mention it on your review. I'd be grateful to know.
