There's already a GURPS Conan, and it's quite good (major influence on HOT SPOTS: THE SILK ROAD), so...maybe Ben Bova's Star Watchman books? I enjoyed them at the time, but there's clearly not enough to base a whole game on, so good for a curse.

Okay. You have unfortunately been hit with the curse that makes you adapt a work you liked as a kid into a ttrpg.
What thing are you adapting?
