Much has been happening in the social gaming world as of late. Playdom brought Mobsters to the iPhone; Zynga filed several more lawsuits; and the Chinese government banned the sale of virtual currency for real money.

Which games are gaining steam? Here are this week’s top gaming applications in the 1-10 million monthly active users (MAU) category, according to AppData:

In the #1 spot is verified app Restaurant City, developed by Playfish. In the app, you can start your own restaurant and bring your friends in as waiters and chefs. Like other virtual worlds, you can decorate your restaurant with your choice of furniture and decorations and visit your friends’ restaurants and, in this case, collaborate on your menus by trading ingredients. Restaurant City currently has over 7 million MAU, with a weekly gain of nearly 13 percent, and has been climbing steadily since its launch:

Following at #2 is Crazy Planets, another one of Playfish’s creations. In Playfish’s own words, “Alert! Alert! The robots are on a rampage across the universe! Gather your friends, ready your weapons, it’s up to you to save the universe. Collect crystals, research new weapons and create your own planet as you battle for glory!” Crazy Planets is another example of the growing popularity of social games where users create their own spaces (e.g., planets, restaurants, homes) and compete with, while enjoying the company of, neighboring friends. This week the app saw an increase in MAU of 443,770 – more than half of what Restaurant City saw – but then again, saw a percentage gain of almost 74 percent, a nice number for a weekly growth rate.

Joining Restaurant City and Crazy Planets in the Top Five include Zynga’s YoVille (#3), GameHouse’s UNO BETA (#4), and Zynga’s Vampire Wars (#5). It’s notable that in this batch, four out of five of the apps are developed by leading developers Playfish and Zynga. Both make an appearance – several more for Playfish – with other developers such as Metrogames, Serious Business, and RockYou! for apps Waka-Waka (#6), Rock Legends! (#15), and Hug Me (#17), respectively.
