OK here's my list:-
1) Please, please get rid of Peter Brooking and Trevor Brackley, they are so poor at commentating and we've suffered them long enough now. Bring on Motty or someone of that standard.
2) Better atmosphere to the game, add things like man of the match, chants and lose the annoying 80's electro rock guitar rubbish soundtrack. REAL MUSIC PLEASE!!
3) More weather effects which change gameplay; snow, heavy rain etc. Was touched on in PES4 but needs to be pushed further.
4) Sort the cheating AI out please and stop the goalie blankly staring at the ball whilst its destroying the back of the net. Konami real goalies don't smoke a joint before they get on the pitch!
5) More licenses but that won't happen until EA lose their grip over the FIFA deal.
Anyway had my rant. Konami please take extra notice of point 1. WE ALL HATE THE COMMENTARY!!
