I'm sorry but this new system is going to screw every improvement Konami have done in the past few years to make PES a simulation. Prepare for FIFA 10-esque 'basketball' score-sheets at the end of every game. What I can tell you from the videos and having played the E3 code myself, is that defending is going to be hell in 2012. And not in a good way.
Looks like it is going to be a sad year for football gaming.
Your crazy mate defending was good and calculated. People always marked. Maybe you just didnt get the hang of it.
This run thing wont destroy the game simply because the defending AI is very good the will follow runs whilst pressuring you when your controlling the other player. ITS GOING TO BE BLOODY HARD.
Do you really think those noobie cheats online will have to brain power to comprehend controlling two players at once?
