When you first go to the menu, you should really choose Kick off. This will train you for the other things. It is better to choose only Brazil in the beginning until you’ve mastered the beginner’s thing. To check, you must play Brazil vs. Argentina (you being Brazil). If you win 5:0 or more, then, you can move on to Amateur and so on so forth. You cannot have 5:4 in the test to see if you can go to the next one.
Now the fun can start:
In Challenges, you have three options (one not available in the beginning. They are Comeback and Rout Challenges. The best one is custom challenges and you can create your own challenges and test yourself. This is the locked one. The easiest challenges (usually) are the Comeback Challenges. In the Rout Challenges, there is a goal set and you have to achieve it. These are not SO much fun but they’re OK.
In career, you get to choose a club and go through seasons with that club. It is very fun and you go against clubs from other countries. Career is basically going through seasons with your dream team.
I competition, you have an option between season and tournament (personally, I think international tournament is the best). There, you can choose an international team like Uruguay and there will be a world cup basically the way it was done this year and the past years. There are also other tournaments like the Champions League and the Bundesliga and others.
Here, you can hook up with somebody and have a match. This is one of the best things in this game.
I bet you know what this is.
THERE IS NOTHING REALLY OTHER IMPORTANT IN THIS GAME.
