Playing with Barcelona at the moment. Have uncovered one bad side of the game; all the cards! especially the red ones. Messi, f ex, has been sent off THREE times in around four months of official matches. And I also feel that many of the red cards are ludicrous and I feel the same way about the suspensions. For every single red card I've received, my players has gotten two or three matches in addition to the obligatory match. Deco, f ex, got two red cards in two games (btw his two only games as he's been injured ever since) and was suspended for a total of five matches for incidents not that serious.
Otherwise, I'm displeased with the match engine's 2D speed. I used the fastest speed at the 2006 game, but now that's too fast. Also, I feel that the second fastest speed is too slow.
This is my experiences this far.
