Nice to know the CPU AI has improved.
From what iv watched so far though they don't seem to have created any differences in the AI.
PES used to have an intelligent set up to make teams mimic their real life situations - ie. Barce play like Barce, Arsenal play like Arsenal, and even when a lower league team played a big team they'd be overly cautious or try to nick a goal on the counter.
Made it really interesting when playing in a replay or a second leg of the champions league.
FIFA has always been about the online play for me in recent iterations, its never managed to capture my imagination and be as immersive as PES for off-line leagues etc.
Kinda pining for the old PES which I sunk so much time into. Think it was PES 2009 which was the final hoorah before I jumped ship to FIFA.
