Polyhedron #157 contains two Star Wars-specific articles. I will not be doing D6 conversions for the first of these, out of respect for the author, Rodney Thompson (otherwise known as Moridin of the SWRPGNetwork). "I, Jensaarai" has been previously posted on SWRPGNetwork, and these include D6 versions of the presented material. Rodney, as the author of the article, probably knows best what the D6 versions of his work should look like. Just pop on over to SWRPGNetwork and do a search for "Jensaarai" if you'd like to dig these stats up for yourself.
The second article, "Starships of the Galaxy," is (as far as I know) going to be a standard feature in odd-numbered Polyhedrons. It includes a complete starship description and an excellent map of the ship in question, and conversions of the ship are presented below.
