The Hobbit movies are a mixed Baggins indeed - at once thunderous and thin, like butter scraped over too much bread - but one sequence I love from The Desolation of Smaug is Bilbo searching Erebor for the Arkenstone, while trying not to rouse the titular dragon from his slumber. Don't Wake The Beast is sort of that sequence plus Spelunkified procgen levels and Thief-esque stealth mechanics.
