SPOnG: "Konami knows that it has a lot to prove with its Pro Evolution Soccer series. After being usurped by Electronic Arts' FIFA brand, the Japanese-developed football experience – which was once deemed the definitive simulation - seemed to quietly fade in the back of gamers' minds.
With PES 2011, the team has made its boldest statement yet. Practically everything in the series' engine has been torn down and rebuilt from scratch, maintaining only a sliver of the code's backbone as a base to jump off from. Dramatic changes and renovation certainly seems like a good idea for a series that has been seen to stagnate in recent years."
