both feel like you're watching an adventure RPG walkthrough. both play on a contrast between cute child-like character designs and a cruel dangerous world around them, with some quite gruesome scenes. in both, one of the cast is an amnesiac who seems to hold the key to the mystery that awaits at the final destination of their journey.
