READING COMPREHENSION FAIL.
They can do it but don't because they're worried about taking the risk and it's a team game, it's often much easier to pass than to run but they can do it. It is virtually impossible in PES2010 due to flawed mechanics.
It doesn't matter about what they do in real life - in a fictional 10 minute game where I decide every move my players make I should like to be able to skin a few players when I see fit. If they are at all capable of accomplishing a couple of slick moves and a goal then I think you should have the option to try it when you please.
Even in older pro evos yes you can run round a lot of the players if you so fancy but it's still easier to pass it, but less fun, and not as much scope to make your friends look like idiots.
Mate, honestly your whole logic is "FAIL".
Let's keep this simple; your point was that players like Ronaldo, Messi etc can skin players at will, when ever they pleased. Simply put I countered with the
fact that, that is utter bullshit.
It is precisely as you say; less risky to pass to your team mate then to attmept to dribble all the time. You have contradicted your own argument becuase this is exactly what PES 2010 tries to reflect in the game; If you try to dribble most times you will succeed very rarely, just like in reality. Which means the Messi's cannot dribble past 3/4 defenders avery time, they either get crowded, out-muscled, tackled or fouled.
With practice it will be easier to skip past one or two defenders under certain scenarios I am sure of that, but it will be in no way as ridiculous as PES 2009 and ultimately that is what you want easy, unrealistic dribbling.
