Apologies if a similar thread already exists.
My copy of Dune: Adventures in the Imperium arrived yesterday (great discount through Amazon Warehouse for a “damaged” book!). I’ve read Dune and Dune Messiah and plan to read those again along with Children of Dune for the first time, but what other books do the Dune cognoscenti on this forum deem “essential” for a referee to have read before trying to run a game? (And for what reason(s), if you don’t mind.)
I’m currently running/playing Alien and Star Trek Adventures, so I have time to read before attempting any Dune campaign.
