GameCube Game Based on Edgar Allan Poe? (None – But These Have the Vibe)

None. No GameCube title directly adapts Poe's works. Games with Poe-esque atmosphere (gothic horror, madness, unreliable narrator) on other platforms:

• Amnesia: The Dark Descent (PC/PS4/Xbox) – Lovecraftian, but Poe-like dread.
• The Dark Eye (1995, PC) – Directly adapts "The Tell-Tale Heart," "The Pit and the Pendulum," "The Masque of the Red Death."
• Eternal Darkness: Sanity's Requiem (GameCube) – sanity mechanic, cosmic horror; spiritual kin to Poe.
• Sherlock Holmes: The Awakened (PC/PS3/Xbox) – Cthulhu mythos, Poe references.

Eternal Darkness is the closest GameCube experience to Poe's themes.
