I know some old farmers that take that farmville to heart . last spring I was sitting in Mexico with a friend that is old and he was having someone water his crop or something like that ,since he had no internet down there..
Never played it, but some folks are obsessed with it. I used to play Mafia Wars, but it just got to the point where it was ridiculous. Now I just play the Mind Jolt games (search for them on Facebook), occasionally.
