Innocent Life: A Futuristic Harvest Moon, (also known as Innocent Life: New Harvest Moon, Innocent Life: Shin Bokujou Monogatari (JPN), Harvest Moon: Innocent Life) is a PlayStation Portable game that breaks many of the traditions established in the other Harvest Moon games and also for the game on PlayStation 2. It was released for the PlayStation Portable on April 27, 2006 in Japan and on May 15, 2007 in North America.
Gameplay
The game takes place on the relic-filled Heartflame Island which can be explored by walking or riding on a buggy. Players have the ability to explore the island's ruins and even visit a volcano. All these areas have their own terrain and is said to resemble a tropical paradise.
Aside from growing plants and raising livestock, you also have weekly requests from Volcano Town for help with a job or two (upon going to your Sunday appointments). Usually you would get some items or new tools for thanks.
