Ever noticed how most planets in Dune are total crap?
Giedi Prime is Detroit/Pittsburgh, Salusa Secundus is a hellworld, Arrakis is a hellworld nobody would even visit willingly if it didn't have REALLY AWESOME WEED, Kaitain is a standard Foundation/Necromunda/Coruscant we-paved-everything-over capital, Ix and they sound pretty awful.
And then you have Caladan and it's basically Seattle. There's oceans and it rains all the time. GEE WONDER WHAT THE GOOD GUY PLANET IS?
