I have been a Fifa fan and player since Fifa 97 and in terms of presentation, player improvements etc this is the best Fifa yet, but the gameplay lets it down AGAIN like so many previous Fifas. My review is based on a lot of different parts.
Online Gameplay Pros :
Improved filtering search
More game types
Online Gameplay Cons:
EA servers still not great
Vs friends Pros:
Really good games
Equal chance of winning
Vs friends Cons:
Referee biased a tiny bit towards the home team(but not often)
Career Mode Pros:
Improved on the player developments
Transfers are more realistic
Youth development has been improved
Cup competitions have a tournament tree
Requesting funds is useful
Player Impact Engine has been improved
First Touch Control
Career Mode Cons:
Referee still seems very biased towards the computer
AI defending still isn't that good
Slow defenders can magical catch up with fast players (even if the fast players aren't tired)
Same old boring commentary
The skills game are really good fun but is annoying when you got to do the very last part of each skill challenge, and ultimate team has improved a fair amount.
Overall if you want a good game then buy it, but be warned if your going to play career mode you might get frustrated with the computer and the AI, as those two things in my view need a massive improvement.
P.S. If nobody believes me about the referee being biased etc I have got a few replays that show they are biased.
