If you are a serious sports fan, who likes franchise mode in madden just as much as playing the games, than you will love this game. It is a free online game, where you run your own team.
You run your own soccer "club" (called franchise here). You run everything from your strategy, assistant coaches, stadium size, players, and starting lineup. Once you sign up it takes a few days to get a team registered, but once you ahve read through the rules you should be well on your way to a healthy addiction.
Especially recomend for people with soccer knowledge, but it is fun for people who don;t know anything as well.
