Hmmm.......
My history with FIFA/PES, I started out with FIFA, and moved to PES when number 4 came out, played PES4 and PES5 since then, now I tried the demo of FIFA, 07, on X360.
Graphics are nice and all that, good enough for me anyway, but the first thing I noticed was the lack of response to what I did with the controller, it's not as fast and accurate as in PES, it felt sluggish, and it felt as if when you start an animation, it, or parts of it, has to be played through before you can do something else, so it's like this; you feel in control, then you do something, and your player takes over that control, you wait, you have control again...
The framerate wasn't too solid, went up and down, sometimes it was really sluggish, especially during replays. I think shots were lousy, at least so far, no real power in them, they all seemed weak... They look weird, hard to explain.
Passing and AI seemed fine.
I think for this FIFA to be any good, this year, for the 360, this demo needs to be old, and that has to be why it sucks so bad, in terms of response and just the sluggish feel, if they can fix that I think it might be enjoyable... Doubt it can beat PES6 though.
