Mafia Wars is all about starting the strongest and the biggest mafia family. The way to achieve that in Facebook terms is by inviting and adding more people into the game. The more friends you have, the bigger family you will have. At the same time, make sure you make quality connections—it is no use adding people to your family that would hardly ever be online to play the game with you. Go to Mafia Wars fan pages and look for other people on the lookout for additions to mafia families.
