i just rented it, don't know that there is enough improvement for me to justify buying it. At least not yet. I started on professional mode and was amazed at how it made the AI players on my team stopped functioning. For example, I'd play a through-ball and the AI would chase it until he was clearly past the defender and then stop in his tracks for no reason. I dropped the difficulty to semi-pro and it seemed to get rid of the player's allergies to the ball. I'm not sure if it was set up that way because I'm using an MLS team or what. I will eventually get FIFA 11 and I will be downloading the PES demo soon, although I need to get a new hard drive still
