Zynga’s monster hit Farmville is all about community. The game is constantly asking you to interact with neighbors to perform tasks on their farm, getting you to exchange gifts and helping you get each other hooked. Now the game has added Facebook’s “Like” rating to its social options. You just need to visit your neighbor’s farm and click the “Like” button under the neighbor’s list.

One of the most popular varieties of Facebook game applications at the moment is the farming simulation. What started innocently enough with Slashkey’s Farm Town exploded the second that game found fame. Now, there’s a wide variety of other farm game spin-offs. They tend to fall into two groups, ones that focus on a multiplayer experience and ones that focus on a single player experience.

To help keep things organized, Gamertell’s done some rudimentary research on the six most popular farming applications on Facebook. We give you the essential information – the basic premise, focus, maker, number of people player and cash shop information.

So, let’s get farming…

Most people don’t really think of the assorted games and applications available on Facebook as full fledged games. If anything, they’d probably be sorted into the casual game category, due to the fact that the graphics aren’t always stellar, you don’t have to make a serious time investment to play and they’re all browser vased adventures. And yet, if you take the time to get involved in some of Facebook’s most popular offerings, you’ll understand how these are not only real games, but also in many cases mini-massive multiplayer online games.

First, look at Farm Town, a farming simulation game available on Facebook. Over 11,948,800 people play Farm Town as of 12:37pm CST, July 14, 2009. The goal of this casual game is to create a successful farm. As you grow more crops, you earn experience which allows you to buy new buildings, purchase more crops, acquire new animals and have more gift options to send to friends.

But it doesn’t end there. Your Facebook friends who have also added the Farm Town game application to their profile can become your neighbors. You can visit their farms to help do odd jobs for them, like weeding or watering. Plus, players can also visit the Marketplace or Inn. At these locations you can interact with other players who are on at the same time as you…
