It's impossible to play PES at one of these events and produce an objective review. I wouldn't uncritically accept feedback from individuals whose objectivity will be subconsciously compromised. All big PES fans, excited to be there, playing with the immediate 'fresh' feeling of a new PES game, and little time to thoroughly dissect the gameplay. Such factors will undoubtedly cloud ones judgement.
We all know that Konami are great at hiding the flaws in the initial stages, and the game needs to be played for months before we can fully identify the problems.
