A for effort, but too many problems
#1 issue is performance. I have a COre Duo 2x2.13 GHz system which might not be a top end gaming beast, but happily runs anything I throw at it, Running 1 country - CM2010 can take 5 minutes between each match. This just means that outside of the transfer windows, I am having to surf internet / watch TV. FM2009 was 1 min.
On top of that loads of minor niggles where it just gets thing wrong in its responses to you. Like referencing a different comment than the one u selected when trying to respond to a players concerns. Or banning u from europe when the red card was domestic. I cant save a "B team" formation / team for league cup etc.
Too many injuries / red cards. Defence are terrible!
