I've not punched out counters for a good many years, but I still have to shake my head at a D&D review that uses Clue, Risk, Monopoly, and Stratego as his referents. There are a lot of great games out there.
Gygax was involved in hex grid wargames and miniatures wargames before he came up with D&D.
I’m an old AH and SPI wargamer myself. Still have a closet shelf full of that stuff for some reason - Panzerblitz, Napoleon at Waterloo, etc.
I never played it. We had all night hearts and spades instead of studying for finals.
