A funny thought happened: How old is rock paper scissors? Then i thought, what would this same game look like to a Paleolithic hunter? Or if I time traveled and wanted to play a game with one could I teach it so it made sense?
I think rock. Rock is easy, rocks are rocks. Hand is next, replaces paper. Hand controls rock. Next is flint for scissors. Rock knaps flint, but flint cuts hand and hand controls rock.
Rock, hand, flint.
