From what I've played its very smooth and sims a lot more fifa like in that sort of sense, the course of the games seems to be less methodical and worked out, far more variety.
Can't really comment much more than that, havent had a proper play, as I mentioned earlier havent got my converter yet to use my PS2 controller so I've been trying my best with the keyboard
With regards to the online stuff though, I registered online fine, got into a server fine, and into a room. Never actually started a game so whether or not it would have crashed on me I dont know. The loading times between menu's in the network area was a bit slow but no problems as such.
Hopefully the converter will come tomorrow
