Gary: I'm very fond of the Medieval period, the Dark Ages in particular. We started playing in the period because I had found appropriate miniatures. I started devising rules where what the plastic figure was wearing was what he had. If he had a shield and no armor, then he just has a shield. Shields and half-armor = half-armor rules; full-armor figure = full armor rules. I did rules for weapons as well.
Gary: I've been reading fantasy since 1950.
Gary: I would like the world to remember me as the guy who really enjoyed playing games and sharing his knowledge and his fun pastimes with everybody else.
