Game hasn't changed much from the last PES.
Stuff i like to see in PES 2009:
-More game mods such as world tour.
-More lincesed teams , cause I (just because of that) don't play that much of Premier leauge...Also i would like to see more leagues and teams.
-Better music(the music in this game totally sucks!).
-Skill based penalties (In the game is all about hoping that the keeper wont go on your side).
-No lag online.
They don't need to touch gameplay because there is no more room for improvement , and thats about it. I think if they do all of this which isn't such a hard thing to do ( except licensing ) they would get a 10 from me.
