As with all preexistant Rune Factory games, you start the game with a boy named Micah (default name, can be changed). He is taken care of by Shara as his alternate form, a golden Wooly. The main aspects of Rune Factory 3: A Fantasy Harvest Moon are farming, fishing, gathering resources, dungeon exploring, and combat, though later in the game you are able to craft, forge and mix liquids, as well as being able to take care of monsters which you can use as either farming helpers, resource suppliers or fighting partners.
Rune Factory 3: A Fantasy Harvest Moon introduces new dynamic AI, being able to transform into a Wooly, and inviting villagers to tag along with you. There is also a new multiplayer mode so that your friends may join you in dungeon exploration.
