Yes, I play Cityville. Shoot me. I want to shoot the people who play Mafia Wars sometimes, and in the past I kind of did that. For a while there I was fierce, especially after a game glitch gave me 3.7 billion BRM-80 machine guns, but that game eventually bored me and I left the Mafia. Now I live in Cityville and I like it.
Social games are perfect for people like me who tend to live in their own little worlds anyway. Several of my very best Mafia friends turned into sorta-kinda real life friends and that's how I found Cityville, among other joys like Oberon Leather and Pinterest. My Cityville neighbors include family, like my sister, husband and sister-in-law, former Mafia from Portland, Barcelona and Singapore, and real life friends from my hometown and here where I now live. We call or chat each other with things like "Could you send me a Baguette?" or "I need Elevator Doors!" and have intense discussions about how to manage expansion. Like I said, great fun.
Oh, and my City, I'm proud to say, is magnificent.
