I've owned this game for a year.
I hadn't played it consistently for at least ten months.
I just broke it out about three weeks ago.
I can't stop playing this game.

You think - soccer. Dull.
You think - soccer. I could care less.
You think- soccer. It's for dummies.

Right. 
I challenge you to play this game on Normal difficulty level with two equal teams and tell me you did not have fun playing the game and that you did not get beaten rather soundly in your first go.

In sports, statistics don't lie.
To date, FIFA 11 has sold over 9.8 million copies across the major consoles. See this.
To date, Madden 11 has sold over 3.1 million copies across the major consoles. See this.

If you give FIFA 11 even half a chance, you will find a superb game that is full of game modes, variety, challenge and enjoyment that you will have so much fun with you might not even notice it is one of the deepest and most dense sports video games ever made.

FIFA 12 is due out this month.
FIFA 12 home page is here.
Until then, let's discuss FIFA 11, shall we.
FIFA 11 home page is here.

Teams.
Madden cannot touch the number of teams included in FIFA 11. 
Five hundred (500) licensed teams, thirty (30) licensed leagues, fifteen thousand (15,000) players and fifty-three (53) stadiums. 
The breakdown of all this is here.
These should keep you busy for a while.

Game modes include:

Exhibition Match
The basic one match mode.

Virtual Pro
Create a player and use him in every game mode, on-line and off-line. Improve your player by what he does on the pitch in every game he plays in.

Career Mode 
Create a player and work him through a career beginning with the team of your choice (or use your Virtual Pro).
Be a team manager, coach your players, play the games and lead your team to titles.

Ultimate Team
Playing cards are used here to represent players, coaching staff, player contracts, arenas, skill boosts, healing, game balls, uniforms and everything else. Playing matches earns you coins that are then used to buy more packs of cards to improve/enhance your team. Active on-line trading and selling of cards is also a part of this mode.

On-line Mode
Single matches or tournaments can be played this way.

Creation Center
This is an on-line mode reached through your home computer where you create players and teams to be used on your console in either on-line or off-line matches.

Replay Theatre
This allows you to upload your replays (edited by you) to your on-line EA Sports/FIFA 11 account where the videos can be seen by everyone.

The gameplay in FIFA is extremely deep.
You may run circles around weaker teams, but face an equal squad or a squad better than yours and you had better know how to play the game. Formations, strategies, substitutions, passing, set pieces, shooting, defending and especially dribbling are all important. The nuances are numerous in keeping possession of the ball - dribbling is deep as is passing, crossing and shooting. This game is not for the arcade soccer fan.

FIFA 11 has so much playability, you won't even touch the massive amount of replayability the game has until you have played through a full league season - you may then start to scratch the surface...

Don't stand on the sidelines any longer.
Get in on FIFA 11 (and now FIFA 12 - Release Date: September 27, 2011).
