Just a quick update about the Mafia Wars Must-Play Weekend - players now get double mastery for doing jobs in Bangkok other cities. Double loot is also now dropping from fights.
I haven't mentioned it yet, but you can get a "Rack of Vegas Poker Chips" as a free gift from friends. Supposedly those with the most Racks of Vegas Poker Chips will get access to the Mafia Wars Las Vegas beta, and then the items will turn into currency, but given historical trends, there is just no telling what they might be used for.
Also, I saw a notice on one of the must-play weekend pop-ups that next weekend there will also be some sort of event. We will have to wait and see!
