EA's top-selling soccer series continues with FIFA 12, which boasts an all-new "player impact engine" designed to more accurately reflect real-life movement and interactions on the pitch. The physics model takes into account a player's momentum and direction when jostling for the ball for more realistic collisions, which leads to more authentic injuries. Other enhancements to the game include more precise dribbling, improved lighting effects, more tactical approaches to defense, and a refined computer AI designed to make onscreen athletes behave more like their real-world counterparts. FIFA 12 also includes a revamped online portal, where you can seek out friendly competitions, compare your stats with friends, share news via Facebook, and improve your overall ranking by earning experience points while playing matches. You'll participate in weekly challenges, follow updated storylines, compete against rival clubs, and more. ~ Scott Alan Marriott, All Game Guide
