For sure, it's one of my favorite series! At the moment, I'm helplessly addicted to Rune Factory 3. Of all the ones I've played so far, that's my favorite one. Second to that is Harvest Moon 64.
I don't have many of the games. I need more o__o
I currently own Friends of Mineral Town for GBA, which I've been keeping permanently attached to my DS. I also have A wonderful Life for PS2, Magical Melody for GC, Rune Factory 1 and 3 for DS. Hoping to own Rune Factory Frontier and Animal Parade soon. Haven't done research on the new ones yet D=
I will be though as soon as I'm done posting this!!!
