I found an online game where the goal is to keep a 3rd world farmer family alive. You have to take decitions and worry about things like witch crops to buy and plant, do you have money enough to send your kids to school, money enough to buy medicine, do you have to merry your dauther away or meybe send a family member to work in the town (never to se him/her again), etc. and all the time disasters will come to you like drought, pig-desease, refugees that steel your lifestock, corrupt politicians, etc. Very nice little game that of course is made to make you think about the what problems an avarage 3rd world farmer has to fight.
