The third Harvest Moon game on Nintendo DS is the first to take place on a tropical island. After being shipwrecked, you and a family of four must gradually develop the untamed land to make it habitable. Tasks such as planting seeds, growing crops, and raising livestock are once again a key part of the gameplay. The overall goal is to turn the island into a thriving community that will attract outsiders and expand the farmland. Players can choose either a boy or girl farmer and interact with 100 characters in total. Island of Happiness also supports the handheld's Nintendo Wi-fi Connection for online farming with friends.
