Alright people it's time to play harvest moon. Since you're here I'm gonna guess you already have the game right here in front of you. So let's get started.
In sandy storms and rainy dawns you are wondering in the desert because you thought it was a good idea. You find yourself at a dry well and collapse from dehydration. Now you wake up with the sexy harvest goddess who tells you what you need to do. Evidently the brain trauma from lack of water and falling down on your head makes us completely compliant to any and all wishes of this milf of all milfs. So let's get started.
Now do the silly tutorials that always force you to do and once the flower people come in you get an exploit, and an even bigger one once the merchant comes in the next day. Now the flower people Dean and Carol, want a flower. Dean will give you 4 flower seeds until you actually give them a flower. Once the merchant Sam gets in just talk to Dean and then sell them to Sam for buckets of cash. I haven't done this, but exploit away! Until it's patched of course. Anyways, if you never played a harvest moon game in your life Dean is one of the guys you can marry. I suggest the Harvest goddess, but if you picked a girl character that's not possible.
So soon you get Naive Cyril, why do I say naive? Well once you talk to him it's clear and evident, since I'm too nice for my own good, he's the one I'm going to romance for the marriage. Since he's too naive for his own good and needs someone to take care of him, I mean it's not like he's got boatload of money or anything.
A key thing to remember is visit and talk to each person everyday. Yes, I know. But they give you quests to do which will make them happy. Currently you should buy as soon as possibly two onion seeds from Sam. The harvest goddess wants them.
