FIFA 10 server's have been turned off, it is no longer possible to get a platinum.
Besides EA's lack of concern for it's customer base, the physics, collision detections, camera angles, ball control, button layout... among other things need work.
There are two main types of game modes left be played;"Be a Pro" and "Manager". The manager mode puts you in complete control of a team, and gives you the opportunity to play with a team for 15 seasons (38 games a season) in a chance to be number one in the world. "Be a Pro" puts you behind an individual player (player generated, initially you could customize his face by pointlessly registering online with EA servers, which is now turned off and can't be accessed). You build up his skills by completing "Accomplishments". You can change out of this and play as the whole team if you desire.
You can slightly customize team tactics and save them as hot keys on the d-pad, but even after hours of futile tampering with the customization settings it seems that the presets that come in the game are about as dynamic as the tactics can be. Opponent teams will be amazingly aggressive in all attempts to take the ball, but fellow team mates will passively allow balls to walk by them, rarely will they run too a pass, and they fail to successfully pass in fluent motions on a consistent basis. They will not drop a pass unless you call for it behind them. The entire game is engineered around the most rudimentary strategy of running the ball down the side and very inaccurately crossing the ball into a small blurry mess of players rampantly swinging away. In the "Be a Pro" mode, while playing as an individual, a majority of the games (with evenly matched teams) you spend a majority of the time waiting for the computer to interact with you, which gets tiring. The collision detection will be cluttering up your rap sheet by the second season.
If you really love soccer, be careful playing this game if you have high blood pressure.
