Been playing the Facebook Parking Wars for some time now 
Its a simple yet fun game that you will need to interact with your friends! Basically you park your cars on your friends street to gain money, and when you found your friend had illegally parking on yours, you could ticket them! Earn money and badges through out the game!
Typical View of the Street
Badges to gain when you archive their parking requirements!
Buy new cars with the money earned!
Off Topic:
Saw this in the Mini2 forum and first thing come to mind is the Monochrome Badge!
