The thing I find appealing about Dune is how WEIRD it is. There's depth too, but it's weird and it really lends itself to all sort of styles and IMO they all kinda work.
Culture quickly defined by what has already been created could definitely use a shot of weird injected.
On the less weird, but still interesting side there's what's known to English speakers as Adventure Box - it's a translated version of the French monthly magazine J'aime lire which is published since 1977.
I ran across Gravity Falls with my kids not long ago, that was great.
I sometimes wonder what He-Man would have been like if they had spent more than 5 seconds coming up with character names and concepts. The whole universe feels like a rough draft/outline where someone went "we're out of budget, this goes into production as is."
