They've really done a very good job with this this year, there's no question about that.
End of the day, if you like 11 but were left frustrated by things than you'll love this because all those things are all but gone.
Terrible AI for example has been replaced by very good AI. No movement by lots of movement. No pace when clear through to pace when clear through. Replays after every foul to no replays. Nazi refs to balanced refs. Didnt mind the keepers too much in 11 so not affetced by those changes.
It's not perfect, but its very fun and realistic game, cant wait to buy it. And I aint a fan boy. I loved PES until the new generation of consoles but then switched to Fifa from 09. Bought both last year but stopped playing footy games after 1 month.
I'll buy PES this year, and if I find myself bored with it after a while will buy Fifa.
