Buy it for the first bits of obsessive playing but don't be surprised when it turns into a major grind-fest.
I'd say this is just about on par with every other Harvest Moon game. At first it's fascinating, running around and discovering all the new things, meeting all the people, never enough time to do everything so you do a little bit at a time. Then you eventually work yourself up until you have your farm animals and your greenhouse, and you're working toward completing your collections, then you realize you're almost three years in and you've missed half the recipes because you don't remember to watch TV (and there is no other way to get them and they cycle every other year) as well as missed several other guide-dang-its, and you still need to kill at least 300 of a particular monster to collect a thing, and it's almost time for the third fair and you're seriously thinking about pulling the same stuff from storage for your grange display that won you first place the year before (or possibly not even going to the fair at all because they'll all say the exact same dialogue over again anyway), and every morning you're following the same pattern taking care of the milking, the egg gathering, and the sheering, the endless petting of the animals and trying to get their happiness up for the best quality products which will never happen anyway because every stinkin' time it rains they take a happiness hit from being in the barn all day, and suddenly you're bored to tears.
P.S. Real milk cows stand nicely in a stanchion to be milked, chickens lay eggs in nest boxes, rabbits give birth, and NONE of them need petted!
