Sorry if this has been posted before, but somebody over on the evo-web forums has the 360 version and this is what he has to say.
"I've been lucky enough to get hold of a retail copy of the game for the weekend and have been playing it a bit so here are some random impressions.
Overall I do like the game, some of my comments may give you the impression I don't...
I only have WE10 to compare against as I've yet to play the PS2 version of PES 6.
The gameplay overall I'd have to describe as heavy. By that I mean the ball seems to be a bit too slow, the players have clunky first touches most of the time. There seems to be a delay between the player receiving the ball and them doing what you want. This was occasionally a problem in WE10 but maybe it's exacerbated in this game by the overall speed of play.
Other musings:
GOOD
Widescreen - Wide camera, widescreen, loveliness.
Graphics - While not what you might call "true" nextgen there is a nice sharpness to the graphics - especially in HD - without HD you do notice the improvement in pitch textures and the crowd is better than PS2 but still a bit rubbish.
Transfers seem pretty up to date - Ashley Cole is at Chelsea or London FC for example.
BAD
Slowdown - I play with the wide camera and there is some very occasional slowdown with loads of players on the pitch and at freekicks/corners. It doesn't bother me much except for the fact that this is meant to be nextgen and doesn't really look it.
Stuff cut out of the 360 version:
8 stadiums - not a biggie for me as it's the pitch I'm looking at.
Edit mode - Only edit player is left, there are no transfers and you can't even change the player's shirt name - it is not the same as the name seen in the rest of the game. Club names etc. can not be edited.
No international challenge mode - not sure if this is in the PS2 version or not but WE10 has it.
Feel free to ask questions though bear in mind I'm not going to be trawling player stats. I haven't yet played on Live, going to see if I can shortly."
