One thing that blows my mind is how tabletop RPGs appeared roughly at the same time as computers and modern video games but it's pure coincidence
Why didn't tabletop RPGs appear sooner? All you need, in theory, is a randomizer and some paper and writing utensils.
@cwebber Also it looks like there was a version of "Werewolf / Killer being played in the 1920s:

But for the most part it seems LARPs pre-date RPGs.
