@cwebber Because wargames were scratching the itch of the era. Understand that we were also coming out of WWII and both wargames and computers were going through a transformational period.
@craigmaloney @cwebber Wait, wargames way predate WWII, though. H. G. Wells was a gamer, he made and played Little Wars.
IIRC, Gygax originally planned D&D as a duel between the players and the DM but people kept treating it as story-telling.
It might be that RPGs are a unique fluke that wouldn't exist without him and TSR.
@craigmaloney great response!
