Is the game play different? I don't think it is.
I played a guy on UT - we drew 6 games 3-3 - every game a 1 goal game except when I beat him 6-2 once.
We then played 2 games in Seasons and I hammered to the tune of 9-1 over two games, neither game going longer than 60 minutes. He RQ and said he can't play there as it's different. (Game 1 was MUFC v. Everton - game 2 Argentina vs. France)
Seems totally same to me!
