The gameplay is what seals it for me, mate. The way that you move, the way that you have to direct your passes and your shots. In PES, if you press pass, it perfectly directs and weights the pass for you (unless you're playing the CPU and it has to fuck them up so that you lose). In UEFA, there is a "passing assist" bar, and you can turn this to zero and direct everything yourself. There's nothing better than directing a 40-yard pass to perfection and thinking "I did that, the CPU didn't do it for me", and then scoring a goal in the bottom corner because you aimed it there and slammed it in, with no help.
The Champions League mode is actually really good, and will last you until PES7/FIFA 08 is out (the CPU on World Class is really hard - unless you're one of those people who can beat every computer game out there with next-to-no effort, which I'm sad to say I'm not). There's a Challenge mode as well (2-1 down with five minutes to go, that kind of thing), there's the start-with-a-crap-team career mode... Put it like this, it's lasted me since it's release, and I will still be playing it until the new games are out.
Is your 360 online? If so then grab the demo, if not then you could rent it from Blockbuster for a few days. Of course, not everyone likes it (you'll find tons of them on here, being a PES board), but all of the people I know who have played PES and then played UEFA have stuck to UEFA ever since - apart from one guy who likes the cutback glitch with PES6 and loves winning.
I'm a huge PES/WE fan. BUT, i'm a football maniac. Therefore, whatever game gives me realistic football experience i'm with it. Thanks mate, now i'll definitely get the game. Impressed me with the "passing assist" part. I like to play my games like i'm playing real football. Alright i'm on my way to buy me one.
