Critically acclaimed, but with its mature rating, Nintendo fans weren't quite sure what to make of it. The narrative and locations are creepy and unsettling, but the best part is the sanity meter which drops when you encounter enemies, causing visual disturbances and even tricking you into believing your TV has broken. The powerful artifact provides a portal to a selection of previous lives, all of which must be experienced by the player in order to prevent an ancient evil from re-surfacing. Developed by Canadian studio Silicon Knights and originally meant for the N64, Eternal Darkness is a fascinating Lovecraftian romp following student Alexandria Roivas as she investigates a book known as the Tome of Eternal Darkness. Resident Evil 4 wasn't the only standout survival horror experience on Nintendo's under-rated GameCube system.
