As far as soccer games go, Konami's Pro Evolution Soccer series is the Apple of the soccer titles. It's humbling beginnings against EA's license grubbing FIFA series turned into a 'purist' soccer series which garners much fanaticsm amongst fans within this quiet niche of sports gaming. PES 2009 comes from a respectable tradition with an entry that is sure to please anyone who likes soccer. Had it not been for the lack of the key licenses, it would be the perfect soccer game for causal and hardcore gamers alike.
Admittedly, I've never really kept up with the series in it's entirety but PES 2006 was always a staple in my collection because it was a great game to play, even if it was mostly played casually. Going into PES 2009, I've noticed that it progressed by refining the most effective keypoints within the series such as the tight controls, great visuals and smart audio commentary. Another impressive feat for Konami is how it scales and performs on PCs as it plays great with all the settings maxed and even has full XBOX360 controller support to boot. Amen to that.
