The Twist

Cooperative games, especially those like Farmville and other social games, don't often give users much of a moral decision during gameplay. Users operate together in order to further each other's progress and to enhance the experience overall by sharing resources. 

In coFarm, users will all be sharing resources such as money for seeds, water for crops, and tools for interacting with their plots of land. However, each piece of land will have reputation and experience that contribute to an individual user's score in addition to team success. If a particular player's plot is given a larger share of the water, its crops will be worth more and its land worth more as well. In addition, other players' plots doing poorly is beneficial, to a certain extent, to any given player in that their plot is more relatively reputable -- and reputation is everything for each farmer.

So we will give the users the tools to burn. Not just their own plots but the plots of others. It will definitely harm the other player's plot, and the fire may spread (and it will be a waste of shared resources), but it will guarantee a higher relative reputation for the other players.
