For my money, though, the most exciting sales are on two indie darlings. The terrifying Amnesia: The Dark Descent is only $10 direct from developer Frictional, while Tale of Tales is running a "pay what you wish!" sale on a bundle containing its sombre interactive vignette The Graveyard, the dark and fascinating The Path, and Fatale.
