It will be possible in a decade or so should optical/quantum computing take off.
Then you could program each player with their own immense AI and parameters based on their abilities to the nth degree.
At the moment the AI is still rather basic.However all the signs point to this iteration of PES being the best yet.
PES2008/9 were very poor PES2010 a step in the right direction.
I would like to see this .While the gameplay is key and other details could be regarded as window dressing , I like the idea that in international games the anthems will be played to lend a further degree of authenticity.
As in the current CL mode I hope the flags are displayed as usually carried by children with the relevant global association behind them for the relevant continental cup ie Copa America, UEFA , ACON and a 'My Game Is Fair Play'.
If it is not embargoed information are the anthems full length and are they with accompaniment of the crowd ? This rendition of the magnificent Portuguese anthem for instance is accompanied and uplifting:
YouTube - Euro 2008 National anthem of Portugal
It would make a great cut scene.
Or purely musical and abbreviated:
YouTube - Argentina Anthem - Beijing 2008 Football Semi-Final
Maybe not for this edition of PES but next year perhaps along with actual manager's faces perhaps ?
And a great marketing coup to have the Libertadores licensed. It open's up further a new market for Konami away from it's Asian heartland in terms of sales. The Libertadores is still a breeding ground for emerging talents from CONMEBOL and the performances of Estudiantes against Barca last season in the ICC were nothing to be ashamed of.
