In FIFA it's like the players are moving on tracks, sliding around, it's terrible. They tried to change the game to make it more like Pro Evo several times, I saw a PS2 magazine today and the cover was: FIFA 2006, they changed everything!
Anyway, I haven't heard a lot about Pro Evo 5. It'll come out in October in the UK, gameplay will NOT be dramatically changed, only improved. There will be new stadia, improved Master League and a new snowy weather condition, where you'll be able to see breath coming out of the players' mouths.
