The Zynga social game cullings that began with FishVille and Adventure Isle continues this month, as the troubled social gaming giant kills one of the most disappointing sequels of all time.

Zynga rocketed to fame with titles like FarmVille and Mafia Wars. When Mafia Wars 2 launched, the number of players peaked at 2.5 million, but dropped to 900,000 earlier this month, with players complaining that the game just wasn't as fun.

Ready for an MMORPG from the people who made CityVille and Empire & Allies? To put it another way, are you read for Zynga's answer to World of Warcraft?

There comes a time while playing any Zynga game on Facebook for the first time, when the playing must stop... unless you want to ask friends for more "energy" so you can play, or unless you want to pay to keep things going.

Your Facebook friends will help you in the sequel to Mafia Wars. They'll help keep you safe while you take a bat to the knees of some Facebook stranger.

Forget the farms, the adventures, the empires and the allies. Love them or hate them, Zynga will soon release what they're calling their "most bad-ass game to date," Mafia Wars 2.
