FIFA 08:It's the best soccer sim on the market.
Pros:
Good team AI,oppostion AI.
Not too easy,not too hard.
You can create a player.
Fun learning the trick system.
You have a place to practise(The Arena,found when loading games,before the Main Menu screen[You can choose whether to go to the Menu,or play]).
Great replay function(although it still has the goalie-diving-through-player glitch).
Has realistic player characters in-game and in profiles(apart from the created players' profiles;just show an empty black head-and-neck area.)
Cons:
The goalie-diving-through-player glitch in replay.
Annoying if you expect to win from the start.
You can only do some tricks with the likes of Ronaldinho,Wayne Rooney,Kaka,etc.
