Blimey...the late 70's / early 80's...getting on the tube to visit Games Workshop in Ravensden Park, or Games Centre at Tottenham Court Road.... the hardback Players Manual, Monster Manual, Deities and Demi-gods and all the rest.
We had a group of 6 or so going for years, oce or twice a week. D&D, Call of Cthulhu, Carwars, Star Fleet Battles, Flashing Steel, WW1 flying game, napoleonic naval stuff, Vampire The Masquerade, Star Trek...ahh, the joys of geekdom.
Still have most of it in boxes, sold some on E-bay to make space.
