Dowloaded the demo last night, had a good few games on it. My first impressions are that it's definately an improvement over PES6.
+ The graphics look MUCH sharper on a HDTV, bigger improvement than people seem to be making out.
+ Controls seem more responsive.
+ Gameplay feels more realistic to me, seems to vary much more than PES6, where it was either ''pass, pass, through ball, through ball, shoot'' or ''run down the wing, cross, shoot.''
It definately has its downsides though.
- Noticable slowdown which is really annoying
- It's like they've tried to make the weight of the ball more realistic but gone waaay overboard, feels like you're kicking a brick.
*EDIT* - After a few more matches, I've changed my mind about the weight of the ball. It's actually an improvement, just takes getting used to coming from PES6.
