It's a football simulation...Diving is part of football....so it gets put in there.
Fact is you can be punished for it so maybe when all these kids have stopped pressing the dive button everytime someone goes near them...having 8 players and getting hammered 5-0 every game...they will learn diving is wrong.
And whoever said get drogba in for Motion Capture.....Pro Evo don't use motion capture...its all animated which is why it looks smoother than Fifa
