I used to play Mafia wars but it got a bit boring, I think I got to about level 96 or something. And also I couldn't find an item I needed for a mission so I just gave up.
I've played Farmville, Yoville,Frontierville (until they bought another farm in to the game) I only play Gardens of Time now.
I play Yoville, also used to play farmville but long ago, left this game after reaching level 70. at that time level 70 was the last.
