Did you pick up any of these games between 1988-1991?
For me, I think I got the Gettysburg game about the time my family visited that battlefield, summer of '88? Before 1987, I or my group already had Squad Leader, Afrika Korps, and Diplomacy (both PC and board versions). I bounced off ASL when it came out.
Did you stick to Avalon Hill’s wargames, or did you also play in their other sandboxes, too?
We picked a handful of AH wargames in the early '80s, but swung hard for GDW, Victory Games, and Star Trek games (primarily Star Fleet Battles), as well as RPGs.
What thoughts do you have about these sales charts, and the games on them?
The non-wargame popularity is interesting, as I don't recall seeing any of those games outside of a store, nor can I recall meeting anyone who played them, until I joined CABS.
