I've always loved this series. I used to rent the original SNES game and play it for hours as a kid. My family said the game looked boring and they couldn't understand how I could spend so much time running around a virtual farm and watering virtual corn.
I've only played Harvest Moon (SNES), Back to Nature (PS), and Island of Happiness (DS). Back to Nature is by far my favorite out of them. There's so much to do, but it never feels overwhelming. Everything is easy to figure out from the start.
The original will always have a place in my heart but it's a little dated. Island of Happiness is fun from what little I've played of it, but the touch screen only controls can be annoying and needing to talk to every villager every day eats up a lot of the time you could spend making money.
Anyone else who has Harvest Moon, what's your favorite game and why?
