This was a Dragon (no, your eyes are not deceiving you, I said Dragon) magazine article that was the first attempt at role playing rules for 40K. Written by Ken Rolston, it appeared in Dragon 149, and just had some very simple rules modifications to allow roleplaying of 1st ed 40K characters.
I really enjoyed it. Long before Inquisitor or Dark Heresy, Inquisitor Thraan Thaken plied the galaxy in his singleship, armed with his daemonsword Anfauglar and accompanied by his stalwart Ogryn Oog, and several other trusty companions who's names I can no longer remember.
It was definitely not for those who enjoy vast roleplaying rules, and its complexity was more along the lines of original edition D&D. Still, that is the type of roleplaying that I cut my teeth on, and it is what I enjoy best to this day.
Curious if anyone else ever fooled around with it?
