I own it. It's really addicting if you like the Harvest Moon thing, especially since the monsters drop items that you can use back at your place to make new items or sell for profit. It's also fun in that you can chose which aspect of the game you want to persue. You can spend years ("game years," that is) just farming without messing with the dungeon-crawling stuff, or you can ignore the farming (for the most part) and persue the fighting aspect instead.
It's really, really great fun. Then again, this is coming from a girl.
