EA just released the demo of Euro 2008 on Xbox Live Marketplace, and here is an early video of it. As a PES addict, I am surprised how much EA has revolutionized their Fifa series. Players do realistic runs and there are a lot of things that is done better here than in Konami's games. I am in a hurry to right now so you will only see some of the goals from my first playthroughs, where the last one is from the Be a Pro mode.
The controls can feel really sluggish at first, as you really feel every step the controlled player takes. Turning around and changing direction can feel really slow sometimes, but this is something you will get used too - it's just the way the controls work in Fifa. Some would say that making mistakes as a goalkeeper, like on one of the goals (not the first, that was on me), is realistic - but sometimes they just stand on the line and do nothing, even though there's a high ball landing two meters in front of them.
If you were angry to see every shot hitting the 20th row in PES when you first played it, be ready for some irritating moments at first in this game - you really, really have to be light on the buttons, as some balls just fly straight up into the stands even though you press the button really fast. This while standing faced towards the goal without anyone near.
The Be A Pro mode lets you pick one player to control, while the AI controls the rest of your team. You can shout for a pass and you are, in one way or another, always involved in the play. It works good and has been pretty fun to play so far.
