Earthbound is a Japanese RPG in which you play a young boy named Ness in a modern setting. As Ness, you'll gather other young adventurers and set out on a quest to save the world from an evil alien named Giygas. Along the way, Ness and friends discover their abilities to utilize psychic powers to battle monsters and people corrupted by Giygas' influence.
Earthbound is notable for a rabid fan following that continues despite Nintendo's neglect of the franchise in the West since Earthbound's release. The epicenter of that fanbase is at Starmen.net.
