Lot of people are taking up virtual farming on FarmVille (a Facebook game). There are lot of things to do and many things to understand. I stumbled across some really useful posts to help you get started and even deal with things on FarmVille: FarmVille User Guide Unofficial Strategy Guide How to Plant, Plow, Harvest FarmVille - HowTo - Youtube Hope that helps newcomers and veterans on FarmVille. Happy farming!
Some nice info linked there. I live on a vineyard property in an agricultural region, so the idea of virtual farming is a bit of a strange one, though. I imagine that game would be fairly popular with city slickers.
Bill: it has become the number one game on facebook in just about 3 months. It had more than 33 million active users : http://www.insidesocialgames.com/2009/09/01/the-top-25-facebook-games-for-september-2009/
