I found out about the iphone game "Mafia Wars" this thursday, and I think its great.
The idea of it all is that you are a "Gangster" or "Mombster" (or what you want to call it) and you have to gain as much "point" as possible. You can either gain points by figting other players or by doing jobs.
The game free to download from the app store, but you can also by a version which gives you more "Gothfather points"; which you can use to buy extra stuff.
My Mafia ID is: 2000 7540 57
You can also create your own mafia family by adding other persons to your mafia list. You can start by adding me 😉
