I will look you up sir once i become a farmer

Hi, I've read somewhere that there is a possibility to become a farmer! Is there more information on this... how does it work? Do you need to do some jobs in order to save up money and buy a farm? When you do buy a farm, is it only yours or others can live there. What would the farmer jobs entail, would it be like Harvest Moon? Also, does anyone know if i dont want to be a farmer anymore, if i could change careers? Can i apply to be a cop?
