A reader is not supposed to be aware that someone's written the story.
He's supposed to be completely immersed, submerged in the environment.

Vance's fantasy works are well represented in role-playing games. Other than D&D, there is The Dying Earth RPG and in 1999, a French role-playing game was published based on Vance's Lyonesse Trilogy. Also, Talislanta was inspired by Vance's works (so much so that The Chronicles of Talislanta was dedicated to Vance).
Strangely, Vance's science fiction isn't represented in role-playing games. His science fiction settings are just as colorful as his fantasy settings. Any of his worlds offer abundant inspiration. Vance was a man of many interests and he was able to call upon them all to describe vivid and entertaining worlds for his readers.
