I've been streaming the game for the past couple of hours and I have to say, it's different from the demo. Granted, I haven't tried any exhibition games but in Master League it feels a lot slower on 0 speed and the CPU AI aren't as frantic and hectic on defense as they could be on the demo.
I'm playing on Top Player at the moment and find it much, much easier than on the demo and in the four ML games I've played so far (with Liverpool, but still), I've rarely felt threatened by the CPU attackers whereas on the demo, most games ended 0-0 for me.
