well, I guess it would have to do with the area where you live , you know climate and such
when I lived in California melons and grapes were great crops to farm
But in Nebraska and Kansas corn seems to thrive here
however when I lived in England, in the east, sugar beets were farmed regularly
it also depends on your knowledge of farming, I would say not to step out of your comfort zone
or, it really depends on your template, anything that drops big gold near a moongate is good for dexxers, mages can gate anywhere out of a dungeon or Ilsh so they can stray far from moongates
why don't you go down and farm para Balrons , great gold and fat dropps
miasma is nice too
