Farmville
When I first saw my friends playing farmville on facebook it seemed more like a joke to me. Maybe the farmer inside me was sleeping then! later a friend forced me to be her neighbour and thats how it started. I started planting different crops and watching them grow in hours gave me immense pleasure. When harvesting brought virtual money the sense of fulfillment was very real. My farm crops, sheep, horses and buildings grew in coming days and weeks.
My husband always wanted to own a farm house and leave the city for simple pleasures of natural life. I prefer enjoying city life with its benefits and playing farmville…. 
) Look at my farm, those lovely fruit trees, green fields and farm animals!! They give me a sense of ownership…..I even own a house there.
Amazingly 56 million people play farmville within three months of its launch, making it the fastest-growing social game on the internet. For the company (Zynga) it is generating revenues of more than $150 million (£91.4 million) this year.
According to a report of Timesonline “Fanatical farmers bought 800,000 new tractors yesterday and today they will buy another 800,000.These may be virtual tractors, bought for FarmVille, a hugely popular online game on Facebook, but the money that the players are spending is real.They hand over millions of pounds every day in hard cash on cows, seeds and farming equipment to make their digital smallholdings bigger.”
Another way to earn coins is by offering help to your neighbors everyday. To speed up this process, try adding neighbors from active gaming forums and common groups so that you can help more farmers daily. With a constant practice for a few weeks without fail, you will become a wealthy farmer for sure, rich enough to buy yourself a FarmVille villa.
Farmville is so addicting that my firm just shut off Facebook in our network cause most workers spend half of their working hours logged in. One time, our CEO was wandering in the commerce office and to his dismay, each one was playing Farmville. The following morning, we couldn’t go to the site and there is a memorandum circulating about prohibition of social network sites and instant messengers.
