First time I sold some of my D&D books? I don't think I have. Although I can't find the Psionics Handbook. I have all of my 1e and 3e books. Along with Traveller books. All of the 1st edition Shadowrun; I even picked up a friend's 2nd printing Runequest when he got rid of somethings.
That's the beauty of government moves, you never half to throw things away. Although, I did have a (broken) VHS player and some handtools not make into and out of New York.
But the game books -<a href="About That Box in the Basement"> they're in that box in the basement.</a>
