I have the opinion that player individuality is something u can only see in football or any sports games after u play a lot of it and get used to the gameplay for the simple reason that only once ure used to the "regular" gameplay the good and the bad players will shine and differ from the average ones.
I say that because this is something i see plp complain over and over about the fifa series for years now, and i must say that i had that complain too until FIFA08 where i really started playing FIFA as my number one game, once i got used to its gameplay i started feeling player individuality just like i did in my WE time, and at the same time i stoped seeing it so cleary in PES(i belive it was because i stoped playing it very often)...
I do think that some atributes, specially mental ones started to differ players in FIFA only last year(positioning, reaction, aggression) wich was great, for exemple a player like Pazzini who isnt fast or strong was a bit of a flop in FIFA11, but in FIFA12 he is deadly, his mental atributes added to his incredible aerial ability and finishing makes him one of the best strikers in the game.
But yeh, i think FIFA 13 is looking evan better in that department, all the good things that FIFA12 had plus the huge diference in players technic this year is something that makes me really exicted and happy about this new game!
